I've been taking 2000mg of metformin every day for years, no ill effects. I guess I'm one of the lucky ones? Also, I'm a type of monkey more commonly referred to as "human".
Same here, 2kmg every day split between 1 in the morning and one in the evening. I did have Diarrhea at the beginning but that went away in a few days.
I am more forgetful now and a little bit more irritated at times, and I've heard this could be related to Metformin.
