I have been on dilantin for 20 years for seizure disorder called cortical dysplasia. Didn't even know I had it until 2004 when I had a grand mal seizure that lasted too long and different tests were run by my neurologist. It was suggested at that time that I switch from dilantin to something else due to taking it "too" long but all I knew is that it kept me seizure free and I was unwilling at that time to change. Well now here I am in 2006 with the side effects of the dilantin taking the chance of switching meds. Have been put on topamax, have been taking it for about a month. Very difficult transition for me, expecially when the dilantin was stopped all together. A lot of it was "in my head" I believe as I knew the dilantin did work and was not so sure about the other but I have struggled with feeling "hung over" in the mornings, confused, off balance, slow in answering questions, and anxious regarding these symptoms. My Dr. assures me I will adjust as my dosage is increased. Just when I get used to one I have to go up so it is very stressful times for me at the present but at this point I'm willing to ride it out. I have a MRI and a 24 hr. ambulatory EEG scheduled within the next 2 weeks so we shall see the results from that, but in response to side effects.......yep.....at least for me...but some are mind created
