Should have explained better. I've been bipolar for over 25 years. I was put on Topomax 2 years ago, along with Epival and Serequil and this year Dexidrine. I'm the most Drabble I've been for years. I was at 200mg a day Topomax when I picked up my script today my DR up it to 250mg been having some troubles lately so that might be why. But I was wondering about what the max is?
