On 11.22.2005, I had another seizure. We were all at my in-laws' house in another state and I had a full blown seizure. I went to the hospital and they checked me out and released me.
After that incident, the neurooncologist and I decided that this would be a good time to switch to a more advanced anti-seizure medication. The only reason we didn't do it earlier is because switching from one medication to another causes an increased risk of seizures during the transition. Since I just had a seizure, it seemed like now was a good time.
