A NEW PRE-BOLUS TO AVOID A CRASH EXPERIMENT #1:
usually, when i am finished with my swim, i bolus for replacement basal for the 4 hours that i have been disconnected from my pump. 4 hours with no basal, translates for me into 2 units.
however, despite the fact that i do this bolus in the locker room the minute i peal off my swim suit, my BG will spike immediately. its astonishing. i get out of the pool at 70, and w/in a moment, my bg is 130. it takes about an hour for that insulin to kick in and my bg to come back into my target range. an entire hour!!!
now i pre-bolus 50% of my post-swim refuel units (instead of bolusing for 32 gms i only bolus 1.6 units) i usually wait about 45 minutes after i bolus to drink my shakes (when my bg is not in the midst of a spike). however, today, i listened to our FUD SPORTS GURU, Eric, and i only pre-bolused 15 minutes. i waited and then slammed those suckers down. (OH MY ARE THEY DELICIOUS
) so i am trying this experiment to see if this will help me to avoid the usual crash i get. i REALLY hope that this works.
and BTW, just to let you know how yesterday’s experiment went (giving myself LESS insulin post swim to avoid the later crash) well, it was a disaster. hours later i ended up spiking from 100 up to 155. yikes. (and i ended up crashing down into the 40s later anyhow) so that’s why today i returned to my original bolus formula. if i am going to crash, at least let me not spike, as well. 
to preface my numbers for today, i want to say that when i left my house to speed walk to the pool (15 minutes) my bg was 116, but only moments later, when i got to the locker room, my bg had climbed to 130!!! this kind of climb happens often, so it didnt surprise me; i just wanted to let you know a little more about why i get into the pool higher than it would seem expected.
here are today’s stats:
1:25 BG 130
2pm BG 115
2:30 BG 81
3pm BG 73 (bolused 2 units)
3:15 (bolused 1.6 units)
3:30 (drank my Boost Shakes)
now its a waiting game. i am off for the w/end, but i will report back on the results.

PS: as i wasnt able to send out this post asap, and its been about an hour since i wrote it, i tested my BGs and i had crashed down to 52. i took 2 Gtabs and am hoping that that will be the end of my crashing for the night. i’ll keep you informed.
got to love the water!! sometimes, not always, it can work like a charm to bring BGs down.
