I've only been on 25mg in the evening for about
6 days but I do have the stomach problems already. Everytime I eat I can't eat as much as I used to and I also have diarrhea and nausea. It has been helping out with the migraines so far... although I'm verryyy sleepy. Only problem with this is, I'm sleepy a couple hours after I take the topamax but wake up about
5 hours later and can't go back to sleep for at least an hour! Not too fun, especially if my boyfriend doesn't want to get up and talk with me. Luckily, last night we couldn't sleep together. But thats, beyond the point. Topamax is pretty tricky. With these side effects already happening, people speak of the tingling in their hands and feet and I haven't felt any of that yet so far. I expect the cognitive thing but so far not any of that. Hope it works out for you. Talk with your doctor if the stomach problems become too much. He may be able to help you out with that. Sounds pretty common.
