Hi,sorry to hear about your situation things will get better
When I was diagnosed with pre-diabetes and then T2 I had know idea what to eat, my first BG test was 7.8 mmol, I was put on Sukkarto
(Metmorfin) I didn't really change my diet yet on my next appointment it was 5.3. I can only assume that the metformin was the reason.
I did have an upset stomach, first of all and took Lansoprazole but for some reason I got used to it and stopped the Lansoprazole
