Weed withdrawls

at first I didn't really think they were real, but ive been smokin regularly for a few years and I must say, when Im not on the kush things get a little "weird".  Its not nearly as bad as quitting cigs or alcohol (for alcoholics) or even caffeine for that matter and I really think the rehab programs people do are complete bullshit.  some of my friends agree with me and some dont but I've come to my own conclusion that for some people withdrawls do exist.  For me the first thing I notice is my appetite is gone.  in my head i know that i am hungry and when i try to eat something i can only force a few bites down and then start to feel full or even nauseous.  At night its harder to fall asleep and I end up having really vivid dreams that I remember well.  the last thing i experience is just a general sense of anxiety, like a cold sweat mixed with nervousness and maybe a little more jumpy and defensive in conversations. Anybody else go through this or got tips for how to avoid it ?(other than abstinence, dickheads).  I'm going home for a week and wont have access to any greens over break. ive been cutting back these last few weeks so that its not such a harsh transition.
