hypnotism

Hypotheticaly, lets say i want to go to the hypnotist to lose weight does that make me vulnerable to all types of hypnotism until i dont want it any more? Then if i have already been hypnotized for that purpose, would it stop working cause i dont beleive any more?

You would not be vulnerable to other hypnotists. I don't know if the original hypnosis would continue; it may, or may not.

I would argue that in order to change or gain a behaviour one has to first want to change. This want will cause some of the non-resistance during so-called 'hypnotic trance'.

If someone then decides they don't want to change, they most probably won't. Human willpower is a strong thing indeed.

thanks everyone for your replies :)
