I understand your situation. My TN started on my right side several years ago. My MS doctor put me on Trileptal and it worked ok for a while then I had to double it.
The TN then started on the other side of my face. and I was taking Advil as often as I could along with Trileptal.
In September I went back to my MS doctor and let him know that my face pain was not controlled anymore and he added Clonazepam. It helped a great deal with the problems I was having with leg cramping at night and it knocked the face pain right away!
The doctor didnot mention to me it would help TN also, I thought he was giving it to me for leg cramping.
I figured it out just recently though. I went to my MS doctor last week and mentioned the Clonazepam was making me feel very sleepy during the day so he told me to take the Clonaz at bed time and take Zanaflex during the day.
I did that for 2 days and WOW did the TN pain start coming back. I could hardly stand it.
I went back to my 0.5 Clonazepam twice a day. I take Provigil and have started drinking coffee and Pepsi and I manage to find my way through the day. However I do not have a job to go to however I do have 5 children to look after.

I am sorry you are having a difficult time with this. I know how much you need the Clonazepam and to have to wait that long to see a pain doctor is insane!
