I was put on Metformin two and a half weeks ago and managed 1 x 500 every day for 8 days but was too close for comfort for the bathroom 6 and 7 times a day ,I stopped taking them and rang the DN,she arranged a preescription for SR version this has the complete opposite effect on me every day, tomorrow is the last day of the "X Pert" course at my Dr,s so will try to have a word with the DN then,I dont want to have to start taking laxatives and I really do get my share of veggies ,fruit and fibre so dont know what the answer to this problem maybe things will improve with time ?
