opiate withdrawal
"I can't give methadone a horrible review as it does have its place. When your bad off it can get your life back in order. I've been on and off twice. Each time over 2 years on @ around 130mg usually. While on it you can beat drug adiction, so it does save lives, BUT it comes at a cost. Its much more addictive than herion and I did a bundle per shot just not to feel sick (didn't get high) while off methadone in my past. Hard to believe but it's true. Getting off of it is  much harder. Regular opiate withdraw lasts maybe 4 to 5 days. Methadone withdrawal can take weeks to feel normal again making most return to the clinic or start to use again to kill the sickness. Even getting off slowly doesn't make it easy."
