Thanks for the advice... will keep an eye out for fladdicts post.
Yeah, I suffered all that my first time. It wasn't until into the third week I started to feel "better"...a relative term. You might want to avoid the cig's and caffeine, it can make you feel worse when you're like this. Usually does.
I'm going to ask Fladdict to re-post her amino acid post for after treatment.
If you decide to try a benzo for sleep, just be careful. I used a rule that I didn't take them more than two days in a row, and never more than ten days in a month. You should be at a point where you are able to start sleeping a few hours a night soon. So taking them can help. Before two weeks, it's sort of a waste.
Are you taking clonidine? It will help alot with what your suffering.
methadone makes you suffer far longer than say percocet or vicodin. So yes, two weeks is still reasonable to feel this way.
