obesity
"The first week seemed fine enough at first:  tingling in feet and hands, dry mouth, and diet soda tasted awful so I stopped drinking it.  After one week, I noticed the sluggishness when forming a thought, the forgetting things moments after the thought entered my brain, and tingling in my face.  I also had some issues sleeping.

Talked with my doc and she confirmed all of this was normal due to the Topamax, and it was up to me to continue.  I had already purchased the month dose at the time I got my free dose, so I decided to stick it out and try it.  The FIRST day of the doubled dose was absolutely awful.  I felt anxious and my face was numb and tingly from 6am to 6pm, no exaggeration.  I immediately stopped. Lost 12lbs but not worth it."
