I swam 1.5 km tonight. I had to force myself to go because I got delayed with work and talking on the phone, and also had a brainwave about my thesis so really wanted to stay home and work on that, but I hadn't been swimming since Monday and if I want to keep it up I need to go regularly, otherwise I will just stop going, so I went.
I'm really glad I went! It felt really awesome! Much better than my other swims lately. I think it might be that my blood sugar was perfect the whole time and I wasn't high or low when starting or finishing. I had tons of energy and only had to stop because of the bus schedule (buses only run every hour after 9:00 so if I miss one it's bad).
An hour before swimming my blood sugar was 8.2 (148) so I ate about 15g of carbs of various things, like a spoonful of flavoured yogurt, a piece of chocolate, and some popcorn. Then right before swimming I was 6.8 (122) so ate about 15g of some random gummy bear type things I had in my bag.
Swimming took me just under an hour. My watch screwed up, though, and only recorded 1,325 meters because at one point it was paused when I thought it was on. Disadvantage of not being able to see the screen, I can't tell if it's actually counting or not!
Right after swimming my blood sugar was 5.1 (92). I bolused a unit, and an hour later it was 6.2 (112). About 45 minutes after that it was 5.8 (104), and I had some cereal since I didn't have dinner and figured I should have something before bed.
I reduced my bolus from 2.2 units to 1.8 and will do a -10% basal overnight. I woke up low this morning but was 13.8 (248) yesterday, but lowish the day before, so I think that high may have been a rebound. I was low two other times today but also high as well, so I'm not sure if I should reduce settings or not. So confusing.
Anyway, hopefully my blood sugar doesn't go out of whack overnight.
