Hi Mary, Would you mind giving more information on this. I assume this is something available from medical supply places. What particularly is yours called and does it leak. Any additional information welcome. I hate being awaked 1 to 1-1/2 hours before the alarm is to go off. I say "Can't you wake up at 4:00 am? Then I'll have time to go back to sleep." But of course, it doesn't work that way. Carol Horner cg for Walter 74/21
