Hi carrylyne welcome

all 3 of the meds you mention are used quite often for controlling the pain of t.n. ,so I do not see any bad by using what works for you. as long as you are going by what your doctors prescribes and not uping it or trying other things without doctors advice..as far as med I mean.. holistic methods are fine to try like reiki or vitamins and such..
I think you are doing the right thing .
Maybe others will be by to post what they think but I am sure the meds you mentioned are used allot for t.n. and heck thats about all the doctors,neuros will do untill it gets unbearable and then surgerys become an option. I pray the meds continue to help knock down the pain and controll it for you.

let us know how things are now and then and I wish you low pain always and forever.
If any of us can help you let us know ...keep in touch .
PEACE
