Apologies if this is a bit too early in the morning for this but how long on Metformin before the dreaded trips to the loo??? I have been on this since February with no problems so far BUT.......oh dear.....two trips on Thursday morning, two on Friday, zero over the weekend and its only 9am and I've been twice. Horrid.....not had much to eat in fact I had porridge for tea last night and am feeling queasy just now. Seeing nurse today in afternoon about things, so will add this to my list.
