migraine prevention
"I've been taking Topiramate, 50mg twice a day, for several years. At first, it worked great and I was recommending it to all my migraine sufferer friends, but gradually, week by week, I seem to have built up a resistance to it and recently, the migraines are back with a vengeance. I have a condition that causes the migraines and I get them most days now. Also, I can only take paracetamol as I take blood thinning medication and it doesn't work for me at all as a painkiller. 

The side effects I personally get with Topiramate are negligible compared to the pain of migraine, I have 'brain fog' now and then, temporarily forget words, peoples names, etc. 

But it's back to the Dr. again now to ask for an alternative preventative - if there is one"
