Dear Jason,

Many thanks for your help Jason. I have now lost over 3 stone and feel so good. This picture of me is in my first pair of size 12 jeans in over 20 years. It is just amazing how it has worked. I now love my daily walk.Thanks again for all your help. I would have no hesitation in recommending Jason to my friends and colleagues.

“Hi Jason, how you doing. I am going great since we last spoke, down just 2 stone and finding I feel much better and have a lot more energy each day. Walking daily and listening to my stomach has made a lot of difference. My friend Kelly was recently in with you also after I told here about you and she is nearly down a stone already. So both of us are looking forward to a nice shopping spree soon. Thanks so much”

Thanks all. Should have got the hypnosis done years ago. Flight was quite pleasant and hopefully will be the same on way back. Just shows the power of the mind. Thanks to Jason O’Callaghan for making it happen for me. I would recommend a visit to Jason for anyone suffering a phobia to get it sorted once and for all.

But now after undergoing a course of hypnosis with Jason, Sharon has lost almost 5st without even trying.

“I went down to Jason in the clinic and since then I haven’t looked back.”
