Hi Sue K

I take topamax 50mg am and 50mg pm. I acually can't say if it really helps with the nerve pain that much. But I can tell you for me I really don't become drowsy with it but then everyone reacts differantly with medications. I wouldn't be afraid to try a new medication.. You never know what may work for you... I found that Cymbalta helped me more than some of the others and I didn't put as much weight on with it as I did when I was taking neurontin.
As Frogga said you can give it a try and if it doesn't work for you then you still have the Oxy to fall back on.
Wishing you the best...
Gentle Hugs
