I've been on it for three weeks. I've experienced just about all of it. Excessive memory loss, lack of coordination. SLOW thought process; extreme appetite loss. Yesterday, I had the tingling sensations throughout my face and body for four hours straight. I even noted double vision once. My memory loss is unbearably embarrassing, but I'm managing to cope with it. I had constipation so bad that I cried, and thought I needed a laxative. Anybody who's been on it for awhile might can tell me how it does after a month or so? I'm on a 50mg, for migraines. Also, on Xanax XR if that helps. But, does it get worse? I read it gets better, and more manageable? Should I get off of it before my memory is lost for good?
