Effects of Stress

I just got home from a two week vacation in Canada and it was such a relaxing trip...and I didn't just feel relaxed, my bloodsugars were proof.
Like I had found the day before the San Jose Triathlon and always do during finals week of school, stress makes my insulin needs go up 50% in terms of basal rate and boluses.
On the trip I had to decrease my night time basal rate by 0.15 units and covered meals less. After I woke up so low one morning I was disoriented (only second time in my life) I decreased my nightime basal by 0.05 and still woke up at 43, so decreased it again, waking up at 56, and again, waking up at 85 finally. The last morning however, I woke up at 220. The only thing I can atribute that to was the stress of travelling home to San Diego, even though I wasn't worried about the trip, or at least didn't think I was!
After San Jose I e-mailed professional Brazilian triathlete Vinicius Santana (who is also a type one diabetic, and uses HPH and Humolog injections) asking him whether he has increased insulin needs the day before a race. He says that he takes 3x his usual daily insulin total the day before a race and those needs stay high for up to a week after ironman distance triathlons because of the stress his body is under.
