What I am trying now is to find hunger not too unpleasant. It feels unpleasant at first, then if you think about it, it’s not painful, it’s just different.
Like smoking, temptation is difficult to resist, so things like working in a place with no access to food is a must have. And filling days with activities which make you think about something else also works. I have really bad sleep sometimes, and when I do, my resistance to temptation is less efficient. So you need to know that kind of stuff about yourself.
I don’t know man, just do what you can.
