I set up a daily repeating task for each of the several medicines I take that are due at 7 am (breakfast) and 6 pm (dinner). I have a Pro account so that I can receive push notifications to my iPhone, so whenever I hear the cowbell go off, I remember that it's time to take my medicine. If I ever forget to take the medicine, I delete that day's task so that I can look back at my completed tasks and be able to easily see how often I've missed taking the medicine at the correct time.
