1200mg a day. Two 300mg extended release tablets in the morning and two 300mg extended release tablets in the evening.

I am now on Topomax. My psychiatrist has been having me go up to a "normal" dose very slowly though, to avoid any side effects. I am now taking 100mg a day of it, and I've been taking it for over two months now. She wants me to get up to 200mg a day, but will probably only go up to 150mg a day when we increase the dose next. The biggest problem with that is that until I get to a high enough dose, it isn't really helping that much yet. However, I did notice some issues when I missed a couple of doses this weekend, so I think it may be doing something, even if it isn't that obvious to me!
