ive come off coke, meth, adderall, oxy, methadone, heroin and more

I would have to say by-far the worse was methadone. It is alot harder to come off of then oxy or heroin. Heroin and oxy are about the same when it comes to withdrawl intensity. Heroin and oxy WD's will be really bad for about 2 weeks then start to get better with you being mostly done detoxing after a month. With methadone the worst withdrawls peaked at about 3 weeks and I would say I wasn't done detoxing for 6 weeks. MY GOD IT WAS HELL
