Nice one, Dyna-Ti.
You certainly have my respect! I quit 6 years ago (Over an ounce of hyrdo a week) and it was hideous. The main problem for me was the fact that all the positive aspects of smoking, such as amazing dreams, the munchies and the general social niceness all died down. At the height of my addiction I didn't dream at all! Kinda of scary, huh? And instead of easing my anxiety, it made it worse.
Like you, the first week or so was horrific. Couldn't sleep, vivid dreams was an understatement, more like terrifying night terrors (maybe a by-product of not dreaming for all that time?)
My little bit of advice, get yourself some Nootropics, maybe start with some 5-HTP. This may help you achieve some REM sleep and generally balance out your mood. I personally used some Valeriam Root Tea in the first week to help me relax, and found the 5-HTP later on in my recovery.
oh yeah, remember not to get too complacent and think "I've got this bitch beat" It's the easiest way to slip back into addiction.
Good luck, Dyna
Peace!
P.S. To that copper spouting his mouth off, do a bit of researech before you start spreading your propaganda. Where did you get your facts, a BBC documentary? I got myself in a mess from smoking, but it was my own fault, not the weed. You live you learn. No hard feeling, chap. Think before you condemn something.
