Last night I took my first dose of Topamax: 25mg for migraines. I didn't expect to feel any side effects with such a low dose but I feel very tired but restless at the same time. I feel like I should law down and sleep but I can't stop myself from shaking my legs or twinkling my toes. It's the only thing I've noticed so far. In six day I up my dose to 50mg a day. Wish me luck.
