Yah, went to sleep at 1215 and then just woke up at 445, I'd been dreaming, then opened my eyes to look at the clock. Since it's a day off, I didn't set a back up alarm, just took note that 3 cycles would wind up at 445am. I'm really amazed at how my physiology has latched on to the 90 minute cycle.
Yesterday while crashed out on the couch with the stove timer set for 1:30 hrs, my husband playing guitar, my daughter on the phone (I seem to be able to sleep through a lot, but I hesitate to try the naps in bed lest I get confused abt night and day !)----I slept deeply and then suddenly awakened as if some noise had gone off. I called out "What time is it on the stove?" My daughter said "you have 3 minutes left". Go figure !
Have any of the rest of you had interesting experiences with the 90 minute cycle? I'm thinking that this might be a very powerful component of the strength of all this....
