Hi I have been on topamax for 5 months now. I first learned of this drug after holidaying in USA (i'm from UK!) and after suffering from horrendous migraines for years, with no relief, finally this drug has really helped. However it is certainly not without its side effects. One thing that i have noticed but no one else seems to have noted, so i'm not sure whether it is peculiar to me or not....is dry eyes??? My eyes are so dry all of the time. I am using eye drops 3 or 4 times a day and this is only since i've been on topamax. I'm interested to see if anyone else has noticed anything similar? Also, noticed facial tingling..(pins and needles like) and feel like i have a chest infection all of the time. I also am very forgetful and where once i was incredibly articulate, my memory is definitely impaired. VERY frustrating and embarassing in business situations....BUT i rarely have a migraine and for that i am thankful!
