First time I have used an extended bolus

So I just had my dinner and usually I do a normal bolus for 161 carbs and had a bs of 104. And what usually happens is I go low for a bit then my meal over powers it and spikes my bs after a few hours so tonight to try and avoid the low I did an extended bolus and did a 50/50 well so far my bs is going up from the food and the second half of the bolus should kick in while I am sleeping but with what I am seeing so far I’m happy with that result. I may have to do this on nights I eat later than I normally do. I hate the lows
