I was given normal Metformin which I took starting with 1 daily working up to 3 daily over 3 weeks. After 3 days of 1500 I started feeling unwell and thought I had a bug, ended up going to see the nurse and she put me on the SR version. Well this morning I woke up feeling unwell again like I had on day 3 of standard Metformin and got sent home from work, last night was day 3 and I took it after my evening meal, and was fine until this morning. I know I havent given this long, but I cant handle feeling this bad. What should I do? Im going to see my GP on Tuesday. I felt really sick and dizzy and like I was going to fall over, when I went out, I decided not to eat so the diarhea would stop, it did, but I had to eat something, and it started again, and the pains were horrible, and still are. Ive not felt this rough, tired, dizzy, sick and out of it in a long while.
