Now I check my sugars often, and some foods are taking me by surprise. Namely rice and white bread.

My question is, if I underestimate my humalog amount, and end up going high when I check it 2 hours later, can I then take a booster humalog shot?

Earlier today I had 1/2 a sub (that I asked for on wheat, but got white), 2 hours later was 285, so I took 8 more units humalog to supplement the 12 I took at lunch.

Can I do this?

Thanks
