yeah i was driving with one eye closed for quite a while, simply because i wasn't on the correct meds yet. pyridostigmine worked great at first until i got hives all over my body, and my primary put me on 5 mg of prednisone which did nothing, your body produces about 7-8 grams on its own, 5mg just means you body drops down to producing 2-3 and using the 5 you give it. For me 25mg prednisone did the trick and i have not had double vision since. But I eventually got other issues and had to take more prednisone and various other meds. You see those adds where this drug has side effects of x, y, z, p, d and q, and I went on and off several drugs until I found a mix that worked for me. It is a journey but you will get there.
