Hi, jmsarge,
I have been on Topamax since April of last year.
I have daily Headaches (post concussion Migraine type/post traumatic).
I have just been elevated in dosage to 200 mg twice daily from a starting dose of 50 mg twice daily, and increased by 50mg over that period til now.
I have had some good Headache reduction with its use.
I have had some mild side effects of dry mouth, fatigue, min foggimess - and of course as is expected with many of these types of drugs, ED. The higher dosings have given me some Asthenia (muscle weakness) but stretching has helped with that; you can also do mild aerobics to help it.
I have a nice informative link to Crazymeds about
Topamax for you. This person keeps information updated pretty regularly, you might find it helpful.
