trigeminal neuralgia
"Was prescribed the drug for trigeminal pain.  Knowing people with trigeminal neuralgia and feeling my pain was no where as severe as some, I felt that it may be a bit overkill for my symptoms maybe we were trying to castrate a mosquito with a machete? In the end I couldn't stand how it made me feel. Put on 8 pounds in just 5 days.  Blood pressure went up and I was EXHAUSTED.  I felt very edgy lost confidence in my stride and though the pain I was experiencing did dull it began to expand to both temples, tingling on lips and hands, worst, I just didn't feel myself.  I felt both drunk and somehow so fully aware of my strange symptoms It was as though I was observing myself from a foot away.  200 mg twice daily for five days."
