I know you are a little upset with my response to you earlier, but I have been reading your thread, and I just wanted to say you are really doing great. I can tell you that both times I went through this, it lasted about 7 days, after that I really started to feel a lot better, by 10 days you will start to feel like your old self again. The withdrawal may be a little shorter for you, may only last another day or two. But you made it this far, just stick with it, and I can assure you that it gets better.
Sometimes your going to feel fine, then out of nowhere the symptoms will return, thats when will get the most discouraged, you have to just keep fighting. For the most part, you are going to have those flu symptoms the whole time. The worst part is not being able to sleep. Ive been told to use Nyquil and lunesta, things like that, and they only worked once, after the first night, I still coulnt sleep, no matter what I did. It makes the 5-7 days feel like a lifetime. What your are going through is a nightmare, I know, but u can do it, your already more than halfway htere, just keep it up and youll be better in notime. Good Luck.
Careful with taking any other medications to help with the withdrawal, you may just end up delaying the withdrawal sickness for another day, or even possibly getting hooked on a different medication.
