Knowing that I’d constantly would forget rubbing the beads every to hours I found quickly a working solution for myself: in iCal I created a new calendar.  (I’m on a Mac, did you guess? You can probably do the same in Entourage or Outlook). Then I setup a repeating alarm with no end data to notify me every 2 hours between 7 AM and 11 PM. I also setup whole day events for my milk days (just in case I’d forget to count) and when I needed to change the beads plus when to register the weight. Then I turned off the visibility of the calendar. The alarms show up on my computer perfectly on time and helps me not having to ‘remember’ nor to pay attention to the clock. Once the program is over I’ll delete the calendar and this will turn all alarms automatically off.
