I’m type 2 diabetic on 500mg metformin 3x a day . Today something really scary happened to me . I made myself a omelette for lunch and took my 500mg metformin . I had a slight headache so took a nap . After I woke up I was going about my day I had a small slice of cheese & tomato pizza within 5 mins I began to sweat , my ears felt blocked and I felt funny , I had to rush to the toilet and had diarrhoea . I wasn’t sure if my blood sugars was low or high so I had a glass of water . My blood strips finished today (just my luck ) so I was unable to check if I had low or high blood sugar. I’m very scared after that experience and not to sure what to do . I also feel a little spaced out and fatigue . Is anyone able to tell me if they have experienced this and what it can be ? Thank you in advance x
