Even pumpers should strive for a somewhat consistent activity level. Bg's can fluctuate for some time after sustained exercise. If you are mostly inactive for many days or weeks and then suddenly start exercising, you'll see your basal requirement drop. If you get a moderate amount of exercise each day, you can better predict what basal profile will work for you on a long term basis. I've found that just walking for 30-60 minutes a day (briskly) gets my basals down from 15 to 13/day.
I sometimes drop my basals during a bike ride from .5 to .3, starting just before the ride. Sometimes I can ride 10-20 miles without snacking or getting hypo, and other times I need a few glucotabs to keep me conscious
. Sometimes I start elevating as soon as 20-30 minutes after the ride. It's frustrating, to say the least. If I keep to my latest regimen of 1 or 2 brisk walks a day, my bg's remain more even keeled for eating, exercising, and during the night.
I DO NOT snack before bedtime. I don't understand why doctors recommend snacking before bed, unless the patient isn't a pumper. On MDI, I'd wonder if each night would be my last. I'd wake up either over 250 (sometimes WAAAY over), or under 40.
