I guess, in the scenario where you are a person with Dual Diabetes, i.e., you already have T1, but then also have T2 due to insulin resistance, just taking more insulin isn't going to be a good way to deal with it as additional insulin will only lay down fat and the cycle will continue.
If great care is taken in that scenario (i.e. a lot of monitoring), reducing the amount of insulin would work.
In your context
@DGTaylor, it suggests that something more than "normal T1" (whatever that is) diabetes is going on.
