I am T2 and am prescribed 3 tablets of Metformin 500mg tablets daily. Can someone tell me what is the specific purpose of Metformin as in: (a) Is it to try and stabilise my blood sugar levels at all times? In which case taking 1 tablet every 8 hours might be seen as optimum, (b) Is it to try and reduce the impact of eating meals on my blood sugar levels? In which case perhaps I should take my tablets at a fixed period in relation to my meals e.g. at the same time / 1 hour after eating / etc., or (c) Is the impact of timing minimal, so I could consider taking all 3 tablets once a day. Any advice will be absorbed and considered. Thank you in advance.
