I stopped taking metformin due to a bad stomach about two months ago and was then put on januvla, but I felt better on metformin should I go back on it
If you feel your symptoms are related to Januvia then yes go see your doctor about it. Did you have the regular Metformin or the slow release version? It can take up to 2 weeks for side effects of either to settle down. Also a good idea to start on 500mg and increase by 500mg each week as long as you feel ok, until you reach the target dose. This is an approach that many doctors use to minimise side effects.
There are various meds available, each with their own benefits, side effects and risks. Reducing carbs in our diet seems to be the most important change we can make, and losing weight if we need to. Meds can also help but food is very important.
