... vision where he said things looked really small and far away (kind of like looking through a peep hole I am guessing). The doctor doesn't seem worried and it has diminished but he still has a couple of times a day where he has these vision problems. Has anyone else experienced anything like this? Also, my second quesiton is that a side effect is that sometimes you cannot sweat and can overheat. Anyone have this trouble? It is winter so we really don't know if he is able to sweat but we cannot continue on this if he can't. The summer humidity and heat alone with cause him to overheat just standing outside. Thanks for any insight
