I don't know what your Dr may have suggested. But mine suggested I start off with one tablet (before bed) for x amount of time till any side effects stopped and then up each tablet over time. That way it wasn't as severe and was managable. I found I didn't get any effects from 1 (I take 850mg) and when I upped to 2 I only had 2 days of discomfort and it was usually after I had eaten so it wasn't too bad. I think everyone is different but give this way a go and see if it makes things easier. But I do recommend the metformin as it truly has been a lifesaver for me.

Goodluck!
