Is it really withdrawl, or is it just like when you come out of a movie theater and the sun is too bright? – you get accustomed to a certain setting (being high, etc) and not having that means your body has to get used to being sober again. Now what are the effects of “withdrawl”? Just a coincidence that they are basically the exact opposite of the effects of smoking weed. Angry vs. calm, insomnia vs. sleeping a lot, no appetite vs. munchies, etc.
