Well officially on day 4 of metformin extended release. It has been so motivating for me to eat better and eat low carb I have already lost two pounds. I was doing low carb all last week and started metformin on Friday. Excited to continue! So far my stomach has felt fine on it but I have been having very loose BM/slight diarrhea in the morning when generally I do go every morning but it's not that loose. It's not painful though so I'm okay with it!
