I wrote a long post about Suboxone withdrawals somewhere on here recently; I have a similar post at my blog about Suboxone, which you will find listed on my profile. It is very difficult to taper off Suboxone unless a person understands the unique characteristics of the med, namely long half life and very high potency. The taper has to be done in 'micrograms', and each step at least a week long; please see my post from my blog for details, as I just spelled it all out there late last night. The problem, as you will see, is that most people taper down to one or two mg, and think they are at a low dose... when in reality they are still at the 'ceiling' level. Read a bit and write back if you have questions.
I am no pro at this by any means but I had a Vicodin habit that was a little worse than yours some years ago. These forums appear to be a hit or miss on replies so I will just throw my 2 cents in. I recently stopped taking oxy and I only used Clonidine. It wasn't easy but the Clonidine was very helpful for the aches and sweats. Especially helpful with that little feeling you get that makes your skin crawl when WDing. As for the sleep, eh, I am going on my 5th day and while I feel really well, I still cannot sleep. Hadn't figured out the sleeping problem yet but hang in there and it will get better. 7 days...thats great. I would have thought you would be passed the aches by now but I suppose everyone is different. I keep myself busy in the late hours to take my mind off of it. I know thats easier said than done but looking at a clock is torture. I have read that l-tyrosine is good for the enery but I personally haven't felt the need to take any so I can't say much on that. Pat yourself on the back for the 7 days you endured and stay with it. Good luck and god bless.
