I think I'm having the same problem with my tablets. I'm on metformin 1000mg twice a day, gliclazide 80mg in the morning and 120mg at night & also on insulin Humulin I, 24 units at night and slowly increasing it. My blood sugar levels have gone up to 10.2 to 17 mmol/L. I've been on them for 15 years now and they have gone up rapidly. When I was first diagnosed they could be anything from 15 to 29.6 mmol/L, I managed to get them down but now they are up. I have to say that I also suffer from anxiety, mood swings, back pain, insomnia and sciatica and take tablets for that too.
So I wonder if I have to change medication to try and bring it back to normal levels. I have to add that I'm a vegetarian and most of my meals are slow cooked, boiled or vegetable stir fry with as little oil as I can. Don't have tea, coffee or soft drinks. Don't have large portions of food. Don't do crisps, biscuits and energy drinks.
So it drives me crazy and wonder how I became the size I am as I'm out every day and walk about 5 miles a day to get shopping. Guess I have another underlining problem that's not been found yet? But 15 years and still counting and changing medication amounts is making depressed just thinking about it.
Right I'll stop talking for now and see what people think.
