Thank you all for your replies. I have been on the same dose of Gliclazide and Metformin virtually since diagnosis, almost 4 years ago. I have never been offered anything else. I was told by my previous Consultant that I would never lose weight whilst taking Gliclazide. I am about to have a phone consultation with the DN. This is only my second appointment since February 2020. I was slim until diagnosis and felt very healthy. I can't exercise much since a RTA a few years ago, but I do try to walk every day. The Metformin can cause an upset stomach, I haven't felt really well for about 2 years.
I never eat sweets or biscuits and do try to restrict carbs. I drink a lot of water and never eat rice or pasta.
I was told that I am not a typical Type 2, as it is possible that the condition was caused in my case, because my Husband died suddenly. At that time I lost about 3st in a couple of months and remained slim for several years until I was forced to take Diabetic meds.
