Topamax and cysts

I've been on Topamax for over a year now for what my doc says were migraines. I went thinking I had sinus problems that caused confusion,and forgetfulness. Cat scans and MRIs showed cysts that docs say have nothing to do with anything and put me on topamax for headaches.I started 50 mg at night and stayed that way for a year. At first it seemed the headaches were better and I LOVED the weight loss. I was trying so hard for so long to shed the extra baby weight and over 15 lbs just like that. It caused me to over look what was happening to me. I was becoming an imbecile. Not saying I was a genius but I was a relativly smart woman who could hold a conversation. Now I can barely focus,I have to read things over and over again to try and comprehend them,my memory shot,I lose my words in mid sentence,spelling is horrendous,At times I stutter,my vision is worsening,my body gets achy,I have terrible mood swings ,thought about hurting myself. I cant believe I'm still on this med. All for 15 lbs that I'm gaining back anyway cause I quit smoking. I deserve it for putting my body thru this. I talked to my doctor and I'm weaning off. Nothing a little Tylenol and excercise can't fix hopefully.I just hope the side effects go away and this is not permanent. By the way be very careful drinking while taking this med. I had a very bad reaction to it. PRO-I sleep like a baby ,I will miss that.
