Topiramate Easily the worst experience of my life. I had the worst hallucinations and dreams on this imagineable. Dreams were so gory I threw up in my sleep and had to be woken by my husband. During the day I was unable to respond, I couldn't form sentences, I felt mentally paralysed and I couldn't tell the difference between reality and my delusions. It was terrifying for both me and my family. Worst of all it had a negative impact on my CH with me suffering up to 14 attacks a day.
