HI.. Hang in there ..I was on methadone for 2 years and have not had a pill since april 15th. My legs and arms were jerking very bad also..The hardest part for me was the creepy crawly feeling under my skin & not being able to sleep. Everday gets better. In about a week it is very bareable. two weeks feeling pretty close to normal and by 6 weeks back to the good ole you..The pain that i started taking the methadone for was even worse during withdraws but now has returned ,to the bad but not severe pain i had prior to methadone. I will take this pain any day over constipation, bad memory and the sweet tooth that the methadone did. Who knows what it does to the brain..I'm sure something or we wouldn't go through so many emotional stuff when we come off..Believe me when i say the sun does shine again..You will be so very proud of yourself. I think back on it now and tell myself wow after getting through that I should be able to accomplish anything. I will put you in my prayers so know that someone is watching out for you and he can be the extra strength you need to get through it...hang in there..you can do it.
