There seem to be varying opinions - right from the beginning I was told to take it at night - no mention of with food. I take 2 x 1000mg tablets just before bed and it seems to work for me - never had any stomach issues at all.
I have been told by posters on here that it's not the correct way to take it, but GP and Diabetic Clinic have both confirmed it's fine - so I figure ...... if it ain't broken.............
