I have a 5 year old daughter with epilepsy. She takes 2.5ml of Keppra twice a day. She has been on Keppra since her first seizure last July and we have had issues on and off with anger. We tried giving her 100mg vitamin B6 liquid but it tastes terrible. Is there a better tasting liquid or even gummies we can give her? The one we tried was from Carlson labs and tastes awful.
