Topiramate
"Worst medication EVER.  I couldn't form simple thoughts together.  Couldn't complete tasks.   Migraines got worse.  That was at 100/mg.   200mg was twice as bad.   

Neuro told me I could quit taking it cold turkey.   He's a flipping moron.   I sunk into a deep depression with high anxiety after tapering dose down.   This medication needs to be banned."
