I just went up to the 100mg of Topiramate with the split 50/50 dosage so am hoping it helps. At 75mg only in PM I had 3 more visual auras in a cluster after only 25 days in- between. So right now I am in a lull. I am hoping this works better to spit the dosage and keep it more even in my blood stream. When they did the EEG 10 yrs ago with the Flashing Lights trying to trigger a seizure, it was so terribly painful [the strobe lights that is]. I had a "bad-for-me" headache for 2 + weeks afterwards - anyone else probably would have thought it was "moderate". Recently, I had another EEG done without the Strobe lights, and it didn't show the brain waves with spikes like that first one. I'm sure it was the strobe lights that did it! This EEG was normal.
