yeah I don't think it's necessary to resist the urge to eat when you're stoned. The same applies to sobriety; you can have huge portions, it just needs to be the right type of food. Things that are high in fiber usually are more filling. When I get wicked munchies, I eat a huge bowl of grape nuts with skim milk; makes me full for a while. You can add honey to it, which is a healthy natural sweetener.

Don't feel like a victim because other stoners are thinner. Everyone's metabolism is different. I have a friend who smokes on and off in an absolute sense and he'll fatten up good in just two weeks after going back to smoking, but then he'll lose it all after quitting again. It just takes some education on your part to find out which foods you can gorge on and not pack on lbs. Don't feel like the munchies are controlling you, you can guide them in thr right direction by eating the right stuff.
