As was already said, a 137 is not low...it was either a false low (which I've never heard of as causing something like what you experienced) or something else entirely. And remember, if you have a false low, just eat a bit of protein (not soda or anything carby) to stabilize your blood sugar so it doesn't go lower, but yet not higher either so you can get used to the good lower reading.
