your wrong boris...there is other solutins. what i did. was set my alarm clock for 2 hours after i went to bed...get one of those cd alarm clocks and then crank the volume really loud (dont worry-youll hear it, unless your deaf) and then repeat that 3 times during the night...after a while youll wake up out of habit and you wont need the alarm clock anymore...and dont worry about not getting enough sleep..im sure if your really tired youll fall right back to dream-dream land. after all it IS better than wearing diapers and soaking the bed.
