I fell into type 2 back in 2019 and quickly went from a 11.5 a1c to below 6 in 6 months on Metformin. Now, 4 years later, for some reason it spiked back up to 10.3. Back on metformin. Has anyone had a spike like this and got it back down? I lost about 18 pounds and having a hard time getting it back up. I’m 6’8” 248. Was 265.
