You may wish to consider mixing a little R or V with the H to take
the erratic edge off the rapid lows. Just a thought, it works very
well for Lily.

Glucose tablets are the fastest. Crackers second -- chewing them, the

Ideas, yes. Daughter Lily has pumped for 4 years and does
competitive swimming and soccer as well as recreational skindiving.
All of these activities cause big variations in energy and insulin
First, Lily targets her exercise bg's for 100 to 150, she does not
engage in any physical activity if she is under 80 or over 165. That
must be fixed first. She uses a One Touch Profile which reads 20%
lower than the meters that test the plasma, so calibrate your
During swimming workouts, she needs no insulin + 10grams or more of
carbo an hour just to stay even.
Soccer can be accomodated by eliminating insulin an hour before the
game then reconnecting after. However, usually she forgets to
disconnect until the game, so she needs about 15 grams of carbo to
supply energy during the game, sometimes a couple of glucose tabs at
half time if she's very busy and never stops running.
Recreational swimming is just about a push. If she takes off her
pump, she can go all day with pretty stable bg's if she is in and out
of the water and swimming most of the time. If she gets out for an
extended period of time to play, etc.... she just hooks back up.
Skindiving (with a full wet suit) with moderate swiming (easy stuff)
burns the same amount of energy as competition swimming. She needs no
insulin and must have carbo intake of 10 to 15 grams an hour to
prevent getting low. This is usually taken care of by half a Power
Bar or something like that.
After particularly strenuous activities, her night time basal
requirements will typically run 0.1 u/hr less than normal for 12 to
Your mileage will vary considerably with each activity. You
need to do some simple measurements for the sports and exercise you
do regularly. Do the activity and check bg's every 30 minutes or more
often if they are very strenuous. Correct the bg's with glucose, and
remember to correct for the expected drop in the next 30 minutes as
well so you don't end up crashing.
Likewise, for strenuous activities, check your night time bg's a
couple of times, like 2:00 am and if they are low, again in 2 -3
It is a lot of work to do all this, but once you have a good profile
of body response, you know what to expect. I does get easier, at
least it has for Lily. She is her own woman now, in good control of
her life. She is at Mt. Camp right now on a 3 day overnight somewhere
in the Sierras. I hope to get a letter from her when she returns to
