I was given 50 mg of Lyrica 2X a day for the pain of PN caused from an injury. My experience with this med was not positive. I couldn't think clearly, would want to sleep all day, and would be awake with hot flashes all night. Interestingly enough, it did not seem to influence my appetite, but when I tired to stop this med it was horrible. After gradually trying to stop it, severe nausea and diarrhea would start, which lasted for 5 days. Fortunately, I was able to finally stop it on my second try. Too bad it didn't work for me and best of luck to all of you.
