Has anyone felt like there were having panic attacks, or anything of that sort? I was on it for 2 days. I started at 100 mg Topamax - . The second day I started feeling really scared for some reason? Iv never felt like that to were I couldnt control my body. I was shaking really bad, my heart was pounding so hard and fast. I counldnt slow it down, my body was getting warm fast like burning up. I felt it in my head first and behind my ears, I was lite headed, dizzy, just feeling very weird. I really thought I was overdosing on this? It was scarey. My husband just sat up with me all night, and I havent tryed it again after that..My husband says he thinks I was having panic attacks. All I know is something was wrong. I was put on this for weight loss. For the next 2 days my heart felt so sore.. and now I have headaches everyday. Its only been 4 days now since I started all this..
