I have been taking Topamax (25mg twice a day) for about 2 years now and it has greatly improved the frequency and intensity of my migraines. (I used to have a minimum of 4 migraines per week, and though medications such as Immitrex and Zomig often work, it's still hard to function properly when you have so many headaches. The Topamax has brought that number down to about 1 per week.) The side effects are not too bad, but I am freezing all the time and very tired - complete lack of energy. I almost feel like my head is in a cotton ball, like everything is just slightly fuzzy and I'm a bit disconnected. I wouldn't call it feeling stupid though... I am still able to do my job well; perhaps a slight lack of concentration. Some dizziness, but nothing serious. I have recently started experiencing weight gain, rather than weight loss (not sure if this is related to the Topamax). When I first started taking the medication, I also had that horrible numbness in the tips of my fingers, but that went away. I wouldn't want to give up Topamax now, because I just can't go back to having that kind of pain and vomiting 4 to 5 times per week. Good luck to everyone!
