Do you want side effects? or do you want to know what it does?

Metformin/Glucophage makes the liver quit dumping glycogen on the system and helps the muscles accept the natural insulin available.

Side effects that are most noticible are digestive upsets. If you sneak up on the full dosage ordered by the doctor, it is easier to get through. Half a tablet per dosing for about a week, then the full tablet. Also can take it with Pepto dose!!

It may and may not cause gas, diarrhea or upset stomach.

It is a systemic drug. Meaning it needs to build up in the system over several weeks to be really effective. Missing a dose is not a huge deal. Taking extra because you want to pig out won't do any good.

Metformin really didn't bother me at all. It was the other **** the doctor ordered that gave me stomach cramps.
