Glucose Issue

I went cross country skiing for the first time this year last night!!!!

...and my glucose failed me horribly.  :(

This hasn't happened in years, but I was already low by the time I got to the beginning of the Northern Lights at Kamview.  So I ate a whole bunch of Skittles and a Power Bar and waited around for my mom and brother to ski the Northern Lights.  By the time they were done, my glucose was high enough for me to ski back.  I checked part way back and my glucose seemed to be holding.  Then back at the chalet I was low again.  :/

And of course when all was said and done my glucose went sky high and stayed there for hours despite doing a lot of insulin!  :/

I thought this was 100% my fault.  I ate a starch heavy dinner but didn't carbohydrate count at all so I assumed I did too much insulin.

But then tonight I wanted to go swimming.  I did my normal swimming strategy.  I was much more aware of how many carbohydrates I ate (and so knew I was doing the right amount of insulin).  But an hour later I wasn't very high, and a little after that I was going lower. :/

At 9pm, my absolute last chance to go swimming (pool closes at 10), my glucose was FINALLY going higher.  So I jumped in my car (sad because I normally walk), did glucose (still ok) and jumped in the pool to swim for 20 minutes.  I checked my glucose half way through the swim and was still fine; that's the only reason I stayed for the extra ten minutes (and did some front and back crawl!)  At the end of the swim, my glucose was fine.  I did a little bit of insulin to correct, but it's been going high ever since (even with more corrections).  -_-

So tomorrow night I'm going to stay home and do a basal test in an attempt to see what the heck is going on (without adding exercise to the mix anyway).  I also started a sensor tonight (it's my last one from the box that came with my VEO).  So hopefully I'll be able to figure this out soon!!!!
