All the "have will-power" posts are just too obnoxious. The original poster reminds me of myself in that one of the things I most love about weed is that it tends to obliterate anxiety and worry -- which means it also tends to obliterate will-power. The two tend to go hand-in-hand for me. With the net effect that, although I generally smoke many miles from my house so that I don't have access to the kitchen and am thus unable to cram food down my gullet, when I am at home and have smoked the results are often devastating
Last night I ate a whole box of cereal. The real problem being that it was oat cereal, and I have celiac's disease. Oats aren't as bad for gluten-intolerant people as wheat and barley and rye are, so I'm hoping I don't break out in cystic acne and suffer from a roiling stomach for the days to come, but often following a binge in which I eat foods to which I'm allergic, such consequences do entail.
So, I advise going into each and every smoking session with an objective. Think to yourself, "Why am I smoking weed right now?" every single time before you smoke. If the reason is, "I'm bored," you need to get a life and find meaningful things to fill your time. Drugs should enhance life, not substitute for having a life.
As for me ... I smoke weed to enhance trance music. Or when I'm composing music of my own. Or when I want to walk outside and really, really just open up to nature and feel so good. Or sometimes (with mixed success) when writing fiction. Or to be at ease with friends. Not because I want to vegetate in front of the damn TV with a loaf of bread in one hand and a stick of butter in the other.
