what would make your blood sugar stay low all of a sudden even without the metformin? I had to fast for 1 day and at the end of the fast my BS dropped to 46, since then it hasn't been above 130 and i stopped taking meds because it makes my Bs go to low. its now been a month with no meds and everything seems ok. what gives? can your body heal itself? was I mis diagnosed? I'm confused.
