epilepsy
"I began having simple partial seizures in my adolescent years, not knowing that they were actually a type of seizure but rather a result of lack of sleep and stress. I had two seizures in the last fifteen months and was terrified of ever having one again. So I started taking Keppra at 750mg twice a day and have not had a grand mal or simple partial seizure since, which is a big plus. Was drowsy and slept a lot the first couple of weeks but now I'm back to normal. The only major downside is the extreme mood swings; I was always a happy girl and found joy in everything but now I can barely go a day without something upsetting, deeply upsetting or angering me. Hoping to overcome this eventually; I guess it's the price I pay to be seizure-free."
