I've lost 15 lbs in 5 weeks eating low carb during the week and allow myself a little bit of carbs on the weekend (like Sushi). and take 1 500 MG of Meteformin a day. Today I was feeling shaky. Took my sugar twice at it was 77 and 71. Hadn't taken my meds yet and only thing I ate (hours earlier) was a ham and cheese lettuce wrap with onions and a handful of peanuts. I wouldn't think I would start feeling shaky on such low dose of the meds?
