I have suffered from complex partial seizures for nearly 30years, and have tried every drug. However, I was given Zonisamide literally to keep me quiet. To my amazement I have never felt so good however, I have an upset tummy and am having full on but limited fits. I am at present taking 25mg twice a day. Does the upset tummy go and what dose controls seizures completely in a 40yr old woman. I also take 1000mg tegretol p/day. Thanks
