Benjamin Gryner

Hypnosis

Stop letting old patterns run your life.

Smoking, stress, sleep, confidence, emotional eating or another pattern that keeps repeating: I use hypnosis to help you work on what is keeping you stuck. Sessions are clear, personalized and available in Paris or online when appropriate.

Sessions are currently offered in French only.

A few reasons people come to see me

When trying harder is not enough, hypnosis can create another way forward.

You may want to change a habit, feel less overwhelmed or stop repeating the same response: smoking, emotional eating, stress, poor sleep, self-doubt or something else. This is not an exhaustive list. We start with what is happening in your life now and work on the pattern that is keeping you stuck.

I waited three months before leaving a review because I wanted some perspective. In early January 2026, I decided to start the year by quitting smoking. After years of unsuccessful attempts, I went to Benjamin on someone’s recommendation, without really believing it would work. I left the session relaxed but still skeptical. I had taken a picture of my last cigarette before the appointment. It really was my last. Three months later, I still had not touched a cigarette—all after a single session. It was as though I had simply forgotten how to smoke. If I had known it could work this well, I would have done it much sooner. Thank you, Benjamin—you saved my lungs!

Benjamin, I truly wanted to thank you for today’s session. I arrived carrying a heavy mental load and a great deal of stress, and I already feel lighter, calmer and more hopeful. The way you listen, your kindness and your professionalism immediately create a sense of trust. You can feel how deeply committed you are to the people you work with, and that makes all the difference. Thank you for this valuable moment and for the care you bring to your work. I look forward to seeing the positive effects take hold over the coming days.

I knew nothing about hypnosis. This was my first experience, and it worked: after just one session, I stopped smoking completely. A huge thank-you!

I went to see Benjamin, and after the very first appointment, my OCD problem was suddenly resolved. I recommend him 100%.

I am giving five stars only because I cannot give more. Benjamin is a magician. Thank you for everything.

I went in skeptical because I knew very little about hypnosis. I was pleasantly surprised. Benjamin explained hypnosis clearly; we talked at length and did exercises, and without realizing it, my unconscious mind was already at work. I left thinking we had “only” talked. Yet when I later faced the situation that had brought me to him, I felt no panic or anxiety. I wholeheartedly recommend the experience.

So kind and genuinely attentive. Thank you so, so much. One session was enough to help me take action and get past what had been holding me back. It completely changed my life.

It is amazing how much better I am sleeping. My children even noticed that I was much calmer, even though I had not told them anything.

I lost 12 kilograms in three months—more than I expected, and without even feeling like I had to struggle. I hope it continues; otherwise, I will come back to see you.

Tomorrow marks five months without smoking, and I could not be happier. I have shared your details with three colleagues who also want to quit. Thank you again.

Thank you, Mr. Gryner—you are amazing! Since our session on Monday, I have not had any episodes of disordered eating. I can also feel fullness again, which had not happened for a very long time. I am genuinely delighted with the result and wanted to share it with you. I started exercising again the very next morning. I even did a set of exercises—I could hardly believe it, and it almost made me laugh!

A quick update one week after our session: everything is going well. No cigarettes and no anxiety. I hope it lasts.

I have not touched chocolate, cake or candy in the 15 days since my hypnosis session. I still get cravings, but they pass very quickly. I may need another session later, but not yet. Thank you.

I saw you on January 21 to quit smoking. The result has been very positive. I may contact you later for a follow-up session, but I wanted to let you know how things were going. Thank you.

I did not believe it would work. I booked a session because I needed something faster than therapy: the repetitive thoughts and obsessive ideas had to stop. After my appointment with Benjamin, I began waking up without those thoughts clogging my mind. One week passed, then two. I am now starting the third week. It feels as though this is behind me.

The session

You will know what to expect before we begin.

We first talk through what is happening and define what you want to change. Then we work with hypnosis. At the end, we take time to discuss what you experienced and what comes next.

1

Clarify

We put your goal into words, discuss what you expect and look at what you have already tried.

2

Build

The session is shaped around how your mind works. There is no one-size-fits-all script and no mystical explanation.

3

Experience

You remain aware, guided and actively involved while your attention shifts into a comfortable hypnotic state.

4

Debrief

We discuss the experience before you leave, so the session and the next step are clear.

You may be asking some of these questions too.

My articles answer common questions about hypnosis, habits, automatic responses and change in clear language.

Useful questions

What people often want to know before a first session.

If hypnosis is new to you, it is normal to want a clearer picture. These are the questions that come up most often.

Can everyone be hypnotized?

Most people can experience hypnosis, but it does not feel the same for everyone. There is no single right way to be hypnotized. The session is adapted to how you focus, imagine and respond.

Will I lose control during hypnosis?

No. You remain aware, present and free to speak. Hypnosis is a guided state of attention, not a loss of control.

How many sessions will I need?

For many concerns, one session is often enough to do meaningful work. Depending on the person, the goal or the number of issues involved, two or three sessions may sometimes be useful. We discuss that together without committing you to unnecessary follow-up.

Does hypnosis replace medical or mental health care?

No. Hypnosis can support certain changes, but it does not replace diagnosis, treatment or advice from an appropriate medical or mental health professional.

Book

Il vous contrôle : comprenez votre inconscient et prenez la main

I wrote this book to explain how habits, blocks and automatic responses are built, and how we can regain more freedom. It reflects the way I talk about the unconscious, hypnosis and change. The current edition is in French.
