I've been on Trileptal for siezures since, Jan '07. I wanted to go off it, but since the doc believes the MS is making me susceptable to them, I'll be on it forever.
Last month, I had run out and didn't realize it for a few days. The darn tinglies, heaviness and numbness in my hands had gotten unbearable. When I realized the lapse, I doubled the doses that day. I was amazed that it really made a difference in my pain level. Now I'm willing to take more in hopes of more relief.
I take 150mg 2xday and 300mg at bedtime. It does make me a bit sleepy, but I take Amantadine in the AM to help.
I hope you get some relief. I swear the sensory stuff is pure HE!!. Let us know.
