2. In the first 21 days of developing the habit, what if i screw it for one or two days like sleeping later than i should for core sleep or sleeping too much (i have this problem, i turn the alarm off without noticing it)?
I know that every person has slightly different sleeping needs so i would only know the answer for these questions by trying it for myself, but i would appreciate some insight or similar experiences you biphasic sleepers have had.
A couple of quick answers (I'm about to head out) :
1. I'm currently sleeping with a biphasic schedule for 5 days per week, and monophasic for the other two. No problem at all switching between them.
The only adjustment I make is to allow an extra sleep cycle for the monophasic days. So if you get a total of 6 hours on biphasic days, allow 7.5 hours on the monophasic ones.
2. I wouldn't worry about stuff like accidentally oversleeping. It happens to everyone occasionally, and all you can do is minimise the chance of it happening.
One distinction I made - particularly in the first month or so - is to only sleep _on_ the bed (or couch, whatever) for the nap; and _in_ the bed for the core sleep. It also seems to help to get up and move around inbetween sleeps - don't just stay in bed and grab your laptop.
Good luck, it's well worth the change.
