Gordie, with an hba1c of 77 your insulin will be nothing but a distant memory!
My daughter is an insulin dependent diabetic (for 23 years) she also has a dreadful sweet tooth, (still has to a degree) she has learned to moderate her sweeties intake over the years - believe me it is no picnic! You really must do something about this, the consequences if you continue to bury your head in the sand will be dire. As a result of my daughter's poor sugar level control in the past she has recently had to have laser treatment on her eyes as there was a danger of her losing her sight because of her poor control, and her determination that "she knew best" (she didn't want to be a diabetic and tried her level best to ignore it) and would not listen to the advice she was given.
Now, she has realised that she doesn't know best and regrets her attitude, and is now more or less on an even keel. It is your turn now to do the sensible thing, go and see your doctor or even your diabetic nurse they will get you sorted out. Please listen to their advice and do what they ask you to do, you will be the one who benefits. The consequences of continuing to eat your sweeties and not following good diet could be dire. You run the risk of blindness, kidney troubles even amputation if you carry on down this road.
For your own sake Gordie seek professional help, everyone on AB has encouraged you to do this in the past, we are not the ones you need to ask for advice any more you must see a doctor.
