Some good tips. I have started becoming interested in polyphasic sleep, where you only sleep for a couple of hours a night but have 2x 25 min naps during the day (there are different options).
It’s supposed to take a week or so to get used to but after that you are more refreshed and better rested despite only sleeping for a total of around 4 hours per day.
I am tempted to try it but it will be difficult in my current job.
This article gives an overview:

This is interesting. I have never tried this technique. I just love a good sleep at night but I would love to hear your statement as soon as you tried it!
I have read that it takes some time to adjust. For the first week or so you are like a zombie but after that you become more refreshed etc and gain back about 4 hours a day! Imagine what you could do with an extra 4 hours a day!!
