Yeah I have felt like that before, infact I feel like that now. I haven't smoked weed since June 17th and it's killing me. It's hard to get weed when your favorite dealer gets busted...and your parents don't give you money. I have to stoop as low as using my lunch money for dat shit. Oh and instead of "craving" it while I'm awake, I always have these dreams when I smoke a really really nice batch, then just melow out for like ever.
