seizures
"I have been on Vimpat for about 6 months, adjunct to Zonegran. It has not helped to control my hormonal seizures yet, so my doctor keeps having to increase the dose of Vimpat. However, now I can't sleep well but feel really drowsy in the morning which doesn't help me at work, where I need to be very sharp. The worst is the chronic constipation. I am always bloated and have major abdominal discomfort since taking Vimpat."
