Been there Dipstick, I know how you feel. It was a big dose of prednisolone (for asthma - great, innit? :roll: ) which made my vision so blurred that I thought was going blind; that's twhen they diagnosed T2. I was told that steroids cause BSugar to rocket - so much so that my GP said there was no point changing my oral diabetic drug dosage until I had been off the steroids for a while. Ask your GP about it - or as Hanadr said, pharmacists are excellent sources of info too. Good luck!
