trigeminal neuralgia
"Diagnosed with TN (glad to learn about it and find out I'm not dying of a brain tumor or something) - the pain is horrific.  I've been on the generic form of Tegretol (Carbamazepine) 100 mg 3x per day for 3 weeks.  I still have episodes of pain a couple times a day, but at least I can walk around, talk and eat without the excruciating pain I had been experiencing.  Only downside is I feel like a zombie - tired, and "out of it" - but like others have said - I'd take that any day over the near constant pain I was having."
