Hi tos8,
I've been on vimpat for 3 yrs. now and it has worked great for me reducing my absence and complex partial sz. and it completely stopped my myoclonic sz. The only side effect I had with the drug that had me worried was a rapid heartbeat and shortness of breath but after awhile that stopped, I also will get dizzy for a few seconds but then it goes away. Just like you the drug made me feel more tired and I slowly got used to it. The one thing I don't like about the drug is that I've gained weight while on it. I also found out that if I take over 400 mg. a day of vimpat it will increase my sz. so be sure and watch out for anything like that. Here's wishing you only the best of luck and May God Bless You!
