Trigeminal neuralgia pain doesn't hurt when I sleep

But when I wake up its starts to hurt again within 40 min

Same is true for me! I can even go two or three hours before it creeps in...i've noticed any stress makes it start.  Or even just something i eat....but it is so pleasant to wake up and not have it.  i rarely take naps but same thing then!  i do know when i take a yoga class it's gone almost the whole class.....and for awhile after.  Anyway it's nice to have that small bit of life without it.

When I'm very busy at work I do notice it less or when I take naps. I'm on gabapentin right now an i still have break through pain but it's not super painful although I would like no pain

We would all like No pain.  You will probably need an add on to Gabapentine like carbamazepine  I found that it helped me for quit a few years. You might need to increase your dosses and drop them a s you feel any pain start to brake through but try it.

I was on oxcarbazepine but I some muscle pain side effects but I could deal with that over face Pain constantly but it lost its potency in 3montgs by its self and thank you for your input I got a script for carbamazepine to try but I could always go back on oxcarbazepine
