I won't lie I did have side effects to the metformin. I initially started on the standard release and found I had lots of tummy upsets. My cousin who also went on it recommended I try the slow release. So I spoke to my doc and she gave me a script for it so I changed. They recommended I take 1 500mg tablet three times a day. I'm terrible at remembering to take tablets plus I'm a shift worker so Instead I went off the Royal women's clinical practice guideline for metformin use in pcos. I take my three tablets of a night. I found this suited me way better and while I still had to deal with a bit of diarrhea it wasn't as bad. Now 5 months on I don't have any side effects at all. So I believe people when they say the symptoms settle lol.
