getting out of hell aint easy
ok, first thing to do you've already done.
second - > stop hanging around with anyone that takes meth. tell them you are doing this and why. make sure you let them know its not them, its the meth. they will understand
third - > destroy your dealers number (very important)
fourth -> tell your (non meth taking) friends to come and look after you for the first couple of weeks, esp. on weekend. all it takes is for you to be occupied and not thinking "what can i do now?" - this is what saved me.
fifth -> drink lots of water or blue poweraide (not to be confused with G

)
sixth -> get a project to fill in the time, keep yourself occupied! - nothing too brain taxing, just something interesting
seventh -> break your pipe if you use one and don't get a new one.
eigth -> st johns wort !!!!! works wonders, as does gotu kola and other chinese herbs. i cannot stress this part enough, st johns wort makes an amazing difference.
ninth -> stop coming here and reading about meth. it will only make you drool
tenth -> walk everywhere you can - this way you tire yourself out by night time and fall asleep.
after 3 months you might not crave it anymore, but, a word of advice, its oh so easy to go back to the hell hole, from here on you will need will power.
if you cant help yourself despite trying all this, you can always wait for it to dry up (you will have no choice then

)
good luck!
