Ive done the iv water thing millions of times,not only is it good if your not able to handle drinking water but also just seeing the needle register is something us addicts crave.I for one am on day two and sad to say but the only thing ive been to doing is twisting the pipe,it indeed takes your mind off the hurt and actually does wonders for the chills and sweats,only thing is im scared to death for when I come down off the meth,then ill start to feel the heroin withdrawal more severe and that combo is no bueno...i experienced it a couple years ago.luckily though this time I have two xanax bars which im only taking in small doses and only when needed and a suboxone 8 mg which im going to make last because ive done the suboxone bullshit maintnence program and....you know what I mean,might as well stay on the dope for that kind of money and the w/ds are longer from that crap.NOW for your back,if its your lower back this is one of the symptoms that cause RLS(restless leg syndrome)so the l-tyrosine would be a big help,everything i mentioned in my earlier post you can find and the pharmacy...exept of course prescription benzos and subs..but the valerian root is an awesome natural anxiety supplement that works wonders at night especially.But with the meth id say if your not gonna sleep(which i didnt for 29 days the last time i went cold turkey),screw it ,im using it right now and its really helping,it takes your mind off it,just make sure you have enough to stay high or some kind of pill or anything that will help you get a little sleep right when you feel like your coming down because you will start hallucinating bad coming down off that crap while kicking dope.thats all i got for you right now but keep me updated im here for you man,were in the same boat....one more thing,the only thing i can stomache as i said earlier is yogurt and the toast......put lots of butter or some jelly on it..always gotta be something sugary..thanks for the heads up on the oranges.talk to you soon.
