I went on it to help with migraines but couldn't tolerate more than 25 mg. That 25 mg helped me with sleep when that was a very difficult issue. Now I'm on something that is so strong that there is no way topamax is doing anything but when we tried to taper I couldn't sleep through the night and gave up. I apparently need to do a really slow taper. No weight loss on that tiny dose.

I wound up at a migraine clinic at a major hospital and was put on 500 mg of magnesium which prevents most migraines for me. I have continued to have bad migraines nearly daily in July and August since then so this year my doctor agreed I could double my magnesium and add 100 mcg of B12 during these 2 months and I've only had 1 slight migraine. I'm happier with than needing another med (although I don't know when I'll get off the topamax).
