We can absolutely not advise you on what to dose, or when. That's solely up to you and your consultant. We can however tell you what works for us. Keep in mind we all react different, not all of us have feet on the floor effect, the amounts of insulin we use varies immensely and you may or may not find things very unpredictable thanks to the honeymoon period.
For me, this feet on the floor effect is very predictable. Apparently it's the liver dumping glucose in the bloodstream to get you going for the day. I figured it doesn't really make a difference if the glucose in my blood will come from food or from my liver, it's the same stuff. So I inject in anticipation, both for food and for the stuff my liver gives me, preventing large spikes.
I don't eat breakfast until many hours after getting up.
Should you decide to experiment, preferably with an OK from your HCP, please be careful, test an awful lot, especially if you don't use CGM/Libre, and keep hypo treatment in your pocket.
