epilepsy
"So I had times where I'd black out and have amnesia. Basically it would scare my parents and after the second time it happened they took me to the doctor. We went through all the test and they all came back normal except for my EEG. it came back abnormal. I was immediately put on keppra and hated every second of it. I started off with 500mg 2x a day. After the first dose I was hallucinating and very confused. The four hour mark was the worst. I was super loopy and couldn't focus for nothing. the medicine caused me to have mood swings and go into a deep depression. My advice if you have any sort of mental illness DON'T TAKE IT.  I've struggled with Bulimia, Anxiety, Depression, and Bipolar disorder for years. Seizures stopped. Wasn't worth it"
