Melina,
I hope you had a wonderful birthday!
As for the carbamazepine (tegretol) what you are feeling is very normal. It is a very potent drug and has many side effects. Thankfully, most do go away in time.
Just a note of caution, please DO follow up with your doctors while on this drug, and DO have the recommended blood work done.

Tegretol was the only thing that ever helped me. I had 80% pain relief while on it. Sadly, I ended up having a very severe allergic reaction to it.
Wishing you the best! Nikki
