the metformin won't cause lows the way some other meds do, but you may be experiencing lows for different reasons. When I started Atkins I got some lows, especially if I cheated some, couldn't adjust fast enough.
Also Trish, your bp is rather low for an overweight adult, and while not being high is good, it seems a bit low. Maybe that is part of it too. Can leave you feeling rather tired when its low. Glad you are seeing your doc, hope you get to the bottom of the mystery.
