Heya.
Thanks for the interesting information on the Dymaxion sleep cycle. You've given me a few useful ideas, mostly the stick to a solid schedule and use off the timer. I've been using my good old wake up alarm. It's a pain to keep setting it though. Upside is I already use the trick of putting it at the other end of the room so I have to get up to turn it off.
I've just started the Dymaxion routine with my boyfriend today. Just had my 3rd nap 3 hours ago. Ok I didn't actually sleep for any of those 3 naps but I'll have a proper nap soon, I hope. The boyfriend faded on me though. After nap 3 he just rolled over and carried on sleeping. I woke him up a few times and he said "I'm just going to lie here for a bit." and passed out again. Oh well. Guess I'm doing it alone.
Lucky for me I've got 6 weeks off to get used to this new routine.
Good luck for when you try the other systems out again!
