This is so exciting to read. I have been interested in trying metformin for awhile and have an enormous inherited (don’t ask) bottle of it in my medicine closet that I’m itching to try out. But will converse w my dr first… I’ve only been CGMing for less than a year, but have noticed a real and significant dawn effect that short of a middle of the night bolus isn’t fixable with insulin alone. Thank you all for sharing – please continue to post your experiences?! (Would also love to hear about any T1s trying any SGLT2 meds…). Thanks! Jessica
