Does anyone take this for pain?

I took 300mg 3x a day for 3 weeks and compared to Tegretol it has hardly any side effects for me...but also very few effects period. Didn't feel like it was helping with the pain much.

My GP told me that often people need to take higher doses for it to work (2700mg/day), so just wanted to hear your experiences with this drug.

For me tegretol makes me quite dizzy and sleepy even at 200mg/day.

My pain is inside the left nostril and mild to modorate and usually more constant, so more of the atypical category.
