Propranolol
"I have read most of the posts,  I am so glad this medicine has helped so many but unfortunately I am one if the few that it did the opposite. I have been on Topamax, a bit effective but I created a fast resistance to it and the constant "idiot" mode, fatige, tingling and memory loss made me decide to ask him to change me to something else. 
Since you can't be taken off Topamax cold turkey I was advised to take 50mg and one 60mg of propranolol, the first 5 minutes it felt like I had taken a good 5 shots of tequila without the gagging. After that I left as if someone had dropped a bucket of ice water on me and then a nasty migraine...4 hours later I'm without a breath barely feeling my legs."
