Hi,
As a type 2 on Metformin and a whole host of other stuff myself, it never has been enough for me. My last result was over 90, so I am about the same as you.... I am on a lot of other drugs but the dapafligloxin (or capa is the sister drug) is working wonders and although doesnt "aide weightloss" it doesnt add weight (though metformin never has either). Sometimes you need medication, sometimes you are lucky and can get by without it.... don't look at it negatively - see the benefits.
I have totally changed my habits since finding I was type 2, and not because its a weight based disease but because it was a shock to me finding out my pancreas was so utterly damaged by a procedure that I can't even eat fruit without getting sick. Think of this as a wakeup call to remind you of what is actually going on in your body and appreciate how wonderful it is to be here (sounding preachy I know but its taken me a while to get here myself).
Also with the carbs everyone is telling you to cut out - DON'T DO THAT without checking its ok for you and you arent doing more harm than good. My kind of type 2 it is essental that I eat carbs with all 3 meals and 3 snacks each day - it regulates my liver and allows it to function correctly - you just need to make the healthier choices in relation to the carbs you choose. Brown bread instead of white is an easier way to start. New potatoes rather than old potatoes...
I am sure you will do well, you have already identified where you are going wrong so I think you will kick this into touch, so what if you need a little help with medicines along the way, sadly diabetes is a progressive disease, how you handle it is the hard part
