Don’t get too aggressive with the insulin upfront. I, personally, wouldn’t even deliver insulin at 160, so you might be leaning a little bit aggressive straight outta the gate.
It does still take time to get to know your body and the feeling of low BG. It affects everyone a little differently and you can expect to have a very strong reaction to low BG upfront until you get used to it. Insulin is a little bit like bourbon. If you have never had it before, it will hit you kinda hard, compared with people who have been drinking it for twenty years.
Even those of us with a lot of experience sometimes get extreme lows that result in critical failure. Just gotta pass along the obligatory warnings, I’m sure that you are aware. Your dosages will be a bit different than your sons. It will takes some time to get to know your settings. You will have lows if you are taking insulin.
If you are honeymooning, your dosages will be inconsistent.
You two are both new to insulin, so it might be useful to talk to one another: Low doses of Insulin
