@JustinMcClanahan @steve9256 I did take metformin for a while, then my numbers were so good and so stable that I was able to discontinue it. There was a point, I think I was on prednisone for something, when my numbers went up a bit so my endocrinologist put me on a higher dosage of metformin. That stabilized my numbers.
I had no bad effects from it, but of course I prefer to take as few medications as possible. No medication is without some side-effects, either immediate or long-term.

I am a new diagnosis, and have been taking Metformin for about 2 months. Last week, my blood sugar had risen from 9.6 to 10.6. Going in the wrong direction. I'm supposed to begin giving myself shots of Trulicity, but I'm awaiting the diagnosis of my thyroid cancer (from 45 years ago) to make sure it wasn't Medullary Thyroid Carcinoma. There are a lot of bad possibilities with Trulicity if that is the kind of cancer I had. I was told by my doctor that Metformin could cause diarrhea but I haven't had that problem.

Hello, @lbhoffman - wondering how things are going with your blood sugar? Were you able to determine your exact thyroid cancer diagnosis to see if you could start the dulaglutide (Trulicity)?

I was just given the prescription for a glucometer and strips yesterday. I've no idea why that wasn't given to me at first. I've been taking Metformin. My bad reaction was metformin and trulicity - severe diarrhea during the night and then at work. My doctor told me to stop the trulicity. Then she put me on janumet and didn't tell me to stop taking the metformin. Janumet has metformin in it (janu'met"). Now I'm only on janumet. Once I start testing my blood sugar, I can report it. I have stopped eating sweets almost entirely. No pasta, no bread, no French fries.
