Prep kits
A bottle of MiraLAX powder stirred into a large bottle of a clear sports drink, often with laxative tablets earlier in the day.
Eight ounces of the mixture every fifteen minutes until it is gone. Split across two doses, half the evening before and half the next morning, unless you were told otherwise.
Volume rather than taste. It is a lot of liquid and the fifteen minute rhythm is easy to let slip, which is what a schedule is for.
The planner turns those numbers into clock times, with your cutoff and check-in worked out from them. For MiraLAX and Gatorade that usually means:
Pick a sports drink that is not red, purple or blue. Lemon-lime is the usual answer.
These are the usual shape, not your dose. Units vary the regimen, the split and the timings, and the sheet your office gave you is the one that counts. Change anything here that differs from yours.
