Hi,
I went cold turkey off of Methadone. I had all of the symptoms you talk about. Iam not going to lie to you, its the hardest thing I ever did. I thought I was going to die. First, you have to drink lots of liquids. I did gatorade and water. Drink it all the time. I know its hard to keep anything down (my husband stood by the bed and forced me to drink). It took a while, but I did start to feel better after a month. You are very brave to do this. Its so hard. Make sure you keep in touch with your Doc. They did give me an IV with lidocane and fluids. That helped alot. Good Luck and my prayers are with you.
