I have long wished to try Metformin, and today I managed to persuade my GP to prescribe it for me. She has given me 500mg tablets to take once daily. They are not delayed release. She suggested I cut them in half, but the patient leaflet advises taking them whole. So should I go against the leaflet and try to cut the tablets in half, or should I just take them once a day? And if the latter, WHEN? I would appreciate any advice.
