For those looking for ways to quit...
I waited till I was in w/d's from roxy 30's. I was on quite a binge, and from some advice from a methadone user, I took one 10 mg methadone for approx. 3 days. That got me thru the worst of the w/d's. I quit the methadone after three days, had no w/d's and have been drug free for at least a month.
If you can force yourself to keep the methadone at a low dose, and only take one 10 mg pill a day for 3-5 days, you'll be amazed at the results. I know methadone gets a bad reputation, and they might be hard or impossible to get them, depending on if you have a source, but if you can get a few, and are serious about quitting, but are afraid of the w/d's, then I'd strongly advise giving methadone a shot. Thery are supposedly highly addictive, so be careful.
Having suffered thru w/d's many times, I can't say enough about them. I got no high from them, just felt normal and missed no work. I even managed to go do my job which is in an intense IT position and also managed to get a lot of house work done.
Just food for thought, and again, use as little as possible and for as short of a period as possible.
My only reason for posting this is that I hope I can help at least one person kick their narcotic habit.
