Comparing Carbamazepine

For Trigeminal Neuralgia: Trigeminal Neuralgia started about 6 months ago. Started the Carbamazepine about 3 months ago and have been having the dosage steadily increased to 200mg 3x/day with an additional 100mg at night. Pain is easily triggered by the slightest touch to right side of my face and I can avoid that for the most part during the day but night time is bad. The effectiveness of the additional 100 mg at night lasted 2 days and pain is just as bad again. At 61 years of age with multiple health issues and on disability because of COPD, not sure how much of this I'm going to be able to take.

For Trigeminal Neuralgia: I am a 6; 5'' 245 71 yr old retired teacher after 30 yrs since 2007. I played 2 yrs NFL n 2 1/2 yrs in ABA n am a night club bouncer wk as a bond recovery agent and security guard at troubled apt complexes. 3 tours in Vietnam I have been shot, stabbed been in neurmous fights n in last 45 yrs have had 11 surgeries ranging from 2 total hip replacements to eye knees nose ankle. Suffice it 2 say I have experienced ' pain .' Have TN for last 16 yrs. Unequivocally, this is the WORST pain I have ever experienced bar none. And as I get older ,as I am told by my Dr, it will only get worse.I was prescribed 300 mg 3x/day but since June of 2014 have been taking 150 mg 4x/daily.now taking 900 mg /day and I can't seem 2 balance the pain.Any insight ???
