I started taking those before there were generics as well. Not ever any
side effects like sleep walking, eating, putting things
in cab instead of frig etc.. until they put me on generics. OMG! I had ALL side effects! Went back to brand & all went away. Major side effect from metformin! vs Glucophage. Anyhow, maybe something similar to these morphine's? I Called Roxanne Westward & they said (CS rep) not that she knew of but not sure. She had to ask..
