Re: Subject: Adjusting for exercise, was: Re: [IP] Skiing

I was intrigued by your comments on exercise.  My experience is similar -
exercise decreases my need for H significantly.  I try to run after
breakfast 3 or 4 (ok, maybe 2) times per week.  I run about 3 miles.  I find
that regardless of how big a bowl of Raisin Bran I eat before the run, my bg
drops 60 points - without a bolus (I do leave my basal rate unchanged).  My
problem is that after this 60 point drop, by BG starts to rise fairly
quickly.  However, and this is the tricky part, if I then bolus, even a
little bit, to counter the increase, 2 hours later I'm low.  If I don't
counter the increase, then I'm high all day.  Inevitably exercise days are
the hardest for me to control.  Ideas?  By the way, I'm new to the group,
have been type 1 for 30 years and have been on pumps for 18 years (not a
typo - Virginia Mason in Seattle was into pumps early, and I was lucky to be
in the right place at the right time).
