Hi R. Thomas,
Metformin (glucophage) can have some nasty side effects, one of which is called Lactic Acidosis. The manufacter has the following warning:
Stop taking metformin and call your doctor immediately if you experience a feeling of general discomfort or sickness; weakness; sore or aching muscles; trouble breathing, unusual drowsiness, dizziness or lightheadedness; unusual or unexplained stomach upset (after the initial stomach upset that may occur at the start of therapy with metformin); or the sudden development of a slow or irregular heartbeat. These may be signs of lactic acidosis.
Aside from the flu, which you don't seem to have, I would discuss this right away with your doctor. Lactic Acidosis is rare, but it never hurts to check out whats going on instead of waiting until something becomes a bigger problem.
