I am taking 100 mg at bedtime for bipolar type II, I was on 50 mg...

I am taking 100 mg at bedtime for bipolar type II, I was on 50 mg for 2 weeks. I told the doctor of the tingling in my hands feet and face and she did not even know that was a side effect of the med. I also have been having some pretty bad anxiety soon after I take my dosage at bedtime. I feel like I am seeing little black bugs every now and then. Other side effects...some short term memory loss, sometimes cant think of the right words, general scatterbrained..but alot of these things i had before I was on the Topamax ...they were just intesified when I started taking it. Well, one good thing has come from it, i have lost 6 pounds in the past 2 1/2 weeks. But that is the only positive thing. I am seriously starting to think it is beginning to trigger a mood swing. (not a good thing) If it doesn't start to improve soon I will discontinue this med.
