I agree, far too high. When I was on the same three drugs as you and my readings were consistently high, very similar to yours, it was recommended that I start on insulin. I don't have the other health problems that you have to deal with.
Hopefully your diabetic consultant will be of help.
In the meantime, it will be useful for the consultant to know how your body reacts to the food you eat. Boring, but worth doing for a week at least even for one or two meals a day.
Keep a record of everything you eat and take a reading immediately before eating your meal and another two hours afterwards. If you snack in between meals put that in your food diary.
If you have a smart phone, apply for a free 14 day continuous glucose monitor, you may have seen it advertised on TV. Attach it to your arm (painless) and take readings first thing in the morning, before each meal and 2 hours after (and if you feel 'off') with your smart phone. Very easy to use, I found it very helpful.

Something to think about, anyway
