I went to a vegan potluck today and could only do a small amount of prebolus because you never know the quantity or type of food there. It turned out to be a huge crowd so lots of food.....unknown, well vegan because it has to be and you have to do ingredients list with whatever you bring. But veggies and beans and potatoes and biscuits and fruit and coconut milk and and and. A little of this and that and I kept adding bolus amounts with my food in front of me as I was trying to calculate it. I guessed pretty close, it's just without my usual prebolus I spiked more than I would have liked, but worth that because it was fun.
And then a few hours later I went snorkeling after guessing insulin...................Kept it to a half hour because I wasn't sure what was going to happen and I was still a little higher from my meal which was beneficial. So of course about a half hour after I was done a drop but only to a 3.8 so not too bad. All in all I was proud of my guesses!
