Hi, I was diagnosed with type 2 Diabetes around 5 years ago. I take Metformin 3 times a day. I have never had A hypo until yesterday. I was sweating, my lips were tingling, face was numb, felt very dizzy but could not settle. My reading at that point was 3.3 then I ate and drank and it improved a lot. Just have not felt well since. Just wondered if the Metformin is not working so well now and if I should approach the Doctor for insulin? Sorry think this has been posted twice
