Glucophage/metformin definitely causes the runs! It will slow down and then go away within a couple weeks though.

I'm a little concerned about the 2000 mg once a day...generally it should be taken twice a day because it works for about 12 hours. The top dose is 1000 mg TWICE a day, totaling 2000 mg a day. Also...were you started at this dose Tishie? Like almost any other med out there, the dose should be tapered up or down...with this med its usually 500 twice a day, then 1000 twice a day after a careful evaluation of blood sugar readings, and often a repeat a1C is involved.
