you see, if we weigh under a certain weight, our bodies may stop functioning properly. So, although you are right, one of the
side-
effects of
Topamax can be
weight loss, and it is used off-label as a weight loss medication, if 98lbs is under a healthy weight for your age and height category, then it may not be an appropriate medication for you.
Mind you, if the Topamax is working wonders for your migraine/headache pain... it might also be a shame to take you off of it...
