Lamictal side effects

I have been taking Lamictal for quite awhile now and ever since I started it my writing has been shaky and terrible. My doctor put me on Propanalol, which didn't seem to work. So, on my own, I reduced my Lamictal from 2 to 1 tablets per day (going only 1/4 tab. at a time), and my writing is much improved, but not totally normal. My doctor in another town and state told me that Lamictal did cause the shakiness and she also went with the propanalol. I don't see my doctor for another 4 weeks to tell him about this. Is there anything that is more effective for this reaction than propanalol? Thanks much. Barb
