I've just joined the site today after recently diagnosed type2.I've lost 2.5 stones in 4wks and I'm still losing about 3 pounds a week.I thought id cancer and for 2wks I was up peeing and drinking water all night.I hadn't been to the doctor for 15yrs but I went and the nurse did that finger prick and it was 27.4.The doc said my diabetes is bad.Im on metformin 1000mg slow release morning and night but through the day my vision is blurry and my left foot is numb.About 6pm I start to feel better.I recently got new tv glasses from opticians but in the evening I can't see the tv through them and have to use my old tv glasses.I see this as a sign my blood sugar is more under control in the evening than in the morning.It's really getting me down and it's depressing me.I've only been on metformin a few weeks and I'm just hoping someone will tell me they take a while to kick in.I bought a blood glugose machine and my numbers seem ok through the day but I'm still getting symptoms of high blood sugar,I think.
