Been on a combo of 3000mg of Metformin and 90mg a day for the last 4 years. Last week I got a bit of a breakout on my face and cheeks of very small spots/pimples and my BS started to stay high, not sure if they are related. I was so used to seeing excellent results; 4s, 5s regularly. Nothing had changed in my diet. Would the combo of meds suddenly stop working so well? I expected it might be gradual. For instance I had 2 scrambled eggs this morning with a slice of wholemeal toast and got a reading of 12.5, 2 hours later. I can't fathom this out.
