I just started 500mg of ER metformin on Tuesday. I just got off the phone with the pharmacist, because my doc's office is closed this afternoon.
Nausea is minimal, thankfully, but what I am experiencing is bad headaches and by about lunchtime (I take mine with breakfast), I feel like I could just sleep the rest of the day. I can barely keep my eyes open.
Normal? Will it go away? Abnormal reaction and cause for concern?
what are y'all's experiences with this?
