After seeing all the fuss here I decided to give BPS a go. Only been 4 days but I already notice the difference.
I was only getting 5-6 hours sleep before due to work and a few businesses, but I was always exhausted as a result.
After 4 days of doing a 1.5 / 3 split I am finding my energy returning and I am actually sleeping even less than before when I was always tired...
It's kind of freaky actually. I sleep less to get more energy.
It's going to be a little awkward to time it sometimes as I often coach in the evenings, but I just need to get up earlier and finish the day job earlier I think!
I was amazed when i worked this out. If you can trim 3 hours a day off your sleeping, then that's an extra 21 hours a week. at the usual sleeping pattern of 16 hour a day awake, that's almost an extra day and a half in your week!
which is 52*1.5 = 78 extra days a year = 2 months extra time.
If you have a day job, the hours stay the same so you just gained an extra 2 months vacation time each year
Bi-phasic sleep is great. It also means I am actually awake when my friends in Europe are online too!
