Hi i am no longer taking metaformin as i have lost weight and am using diet control, my problem is my suger levels keep dropping , sometimes from exercise but sometimes for no reason, for example on waking blood sugar of 6.2 porridge, pear and apple, 2 hours later 4.4 from doing nothing, so if i want to walk my dog i have to keep shovelling in fruit, i don't want to have to eat heavy carbs am still trying to lose more weight, i also have thyroid which they say is under control
