so heres the deal. i got this infp friend who is obese, tries to lose weight, and acts like a heroin addict when it comes to ben & jerry's, soda, junk food etc. he manages to stay away from them occasionally(usually due to bets or other agreements made with other people(he even made a "formal" contract that he had to sign once with our friend)), but relapses eventually(usually instantly after these bets or agreements end). he has done this for about 3 years. usually it starts from something like one ice cream or something and he always thinks that he can stop after this, but 90% of times he cant. during these relapses he goes crazy, about everything he eats for food is junk food and he eats other crap daily.
he is on heavy anti-psychotic medication and they make this craving for crap food even worse, but its not all because of them, they just make it bit worse.
he is also addicted to nicotine and have stopped smoking few times but relapsed, he says its easier to stay away from junk food/candy when he smokes. he stopped smoking few days ago, because he had some mild complications(that basically just scared him) caused by nicotine and his medication. now after stopped smoking he started to eat crap again.
he clearly has some addiction problems(luckily he never got addicted to alcohol, but he also has slight addiction when it comes to slot machines) that he tries to fill with either nicotine or eating crap. he says that he needs something like that to keep him happy. i have tried explaining that he shouldnt treat this problem just forcing himself to stay out of junk food, but that he should treat this addiction problem as a whole, he knows it but doesent do anything about it, even tho he doesent like it(or he likes to eat crap, but overally doesent like to have addictions).
he knows that he shouldnt eat crap that much and should stay away from it completely, because he cant just have a ben & jerry's once in a while, because he simply cant do it once in a while.
everyone in our circle of friends have tried to help him, support him, scare him, guilt trip him etc etc and nothing seems to work. and everyone are getting bored/stopped to even try much anymore because nothing works on him. i think im the only one who still believes that he might be able to do it some day..
anyone got some suggestions on how to help him with this or what not to do? help would be very much appreciated.
