So the average T1 uses a total daily dose of 0.7 units/kg (some more, some less, depending
on insulin resistance, exercise, etc). Since you said your TDD is around 11 units/day (you said 8 units basal and 3 units bolus) and my guess is you probably weigh more than 15 kg (34 lbs), you are likely producing some native insulin.
If you were producing none, what you would see is a fairly rapid increase in BG over a period of a few hours, even without eating. The symptoms of diabetes would return (peeing , thirstiness, weight loss, vision changes) as your blood sugar rises and soon ketoacidosis would start. untreated, that leads to coma and death.
I would not fool around with the experiment you are trying for several reasons (a) you will burn out your remaining beta cells faster as they are overstressed trying to keep your blood sugar under control. This will make control harder in the future. and (b) you risk DKA if for some reason things start to spin out of control suddenly as native production falters.
(c) Extended periods of high blood sugar will cause microvascular damage to your organs (retina, kidneys, limbs, etc).
At a minimum, have some basal insulin in your system to prevent DKA.
numbers in the 10 range (180 mg/dl ) are NOT GOOD.
