Ben i know i read it that Metformin does or can cause blurry vision and after being off of it my vision is much better now and not affected as much by florescent (sp) light. Do a ****** and think you will find it.
I do not know of another better drug some of these are great drug's but there can be some pretty bad side effect's . I am trying sweet ease product by Banyan Botanicals just started on it will post if i have good or bad exp. J.B.
