A ton of smart buttons. Every time you do the task you push the button and a time helper is updated to the next date. If today is beyond that date, update a second boolean helper to show the task must be again!
Bonus if you set a light or alarm to go off of you forget to do it or a reward dispenser to drop treats when you complete the task!

Also, keep it at hand. A refillable bottle is worth investing in. If you like it ice cold, get a vacuum insulated vessel.
