Recommended levels for Type 2 from Diabetes UK are:
HbA1c: less than 6.5%
Pre-meals: 4-7mmol/l (and fasting)
2 hours post meal: less than 8.5mmol/l
Your liver may release stored glucose overnight if you go too low whilst you are asleep - this is why some people wake higher than when they go to bed
As Type 2s still produce some insulin, then it is very, very unlikely that we would get ketoacidosis which is a problem for Type 1's (see Bev's recent thread about young Alex's experience) but we can get into short term problems with very high blood sugars without the ketones. The continual high levels increase our risks of longer term complications - I already had some eye changes on diagnosis which frightened me into action
I'm on both metformin and gliclazide and have had some interesting moments in managing the hypoglycaemia associated with the gliclazide. I also experienced the weight gain/weight loss challenges with gliclazide. I now try to keep to between 1200 and 1500 calories a day (about 130g in predominantly low GI carbs) with daily exercise and have been losing about 1lb a week - irritatingly slow progress and have to keep telling myself that 1/2lb off is better than 1/2lb on. I don't think I could be as disciplined as people like Dodger who manage on a low carbohydrate diet so need the medication to assist rather than do it on diet and exercise alone
I would say it took me about 15 months to get to grips with the right diet/exercise regime for me but I'm now getting a few more hypos than I would like so think I might need to review my medication with my doc once I have my next HbA1c which is due shortly and post my next eye review that is due at the beginning of next month
