It made me vomit constantly. They had to take me off it because it got so bad.
I've been on Keppra for over 20 years and I have no problems with it. I'll admit I don't take the exact dose prescribed. I know my body, brain, and emotional system, better than any doc. And that's how I guide the drugs that I throw inside my body.
I've had a good experience with it. I just need to be sure to take it every 12hrs religiously or I can flop. No noticable side effects, and it's easy on you kidney and liver
Only side effects of it has shown aggression increases meaning you'll tend to get angry more n more easily
