Started Januvia and for the first time fbgl was 90 :)

Endocrinologist said I am probably type two but just did a test for type one markers . My insulin level was 2 and my bgl was 100.8 . That’s on 2K metformin. Anyway I can’t eat just 12 g of carbs meal while travelling so I asked for some additional help. She prescribed Januvia. Normally I am 117 in the morning. I have never seen a 90!
