I am on 1000mg of "Metformin" and started to take the medication on the 19/04 taken 500mg to start with for one week then increase to a 1000mg in the second week. The side effects that I have are metallic tasting mouth, nausea and headache. . But the metallic taste that I had was down to one of the other medications I am taken. The odd side effect that I am having is that the combination of the medications that I take is making me feel more depressed than I was already feeling.
