Hypnosis, for safe weight loss

I’m curious: there are mixed articles in the media regarding the efficacy of hypnosis to curb appetite and help with lose weight.
Is there anyone here who’s actually had the treatment and what did they find the results were like? I would like to hear both sides, and details ie how many sessions did it require, cost, any noticeable side effects?
Thanks!
Thanks Vickie! That’s really interesting. Do you think her success will trigger other people in her social circle, who are overweight to also take it up? £100 is not bad at all.
