migraine prevention
"I haven't had a single headache in the last three weeks on my current dose of topiramate (50mg in the morning, 25 at night). The only side effects I have experienced are a decreased appetite and a tingling sensation in my hands which is only mildly annoying at worst. 
Also found that I became extremely drowsy when drinking alcohol with this medicine. 
Previously tried pizotifen 1.5mg which had no effect on the headaches and caused 15kg weight gain."
