Yesterday I went to sleep after adding 16hours to my wake-up time:
1pm + 16hrs = 5am
It worked, I fell asleep within 5 minutes. At least it felt that way.
Today onward I'm gonna use some info I had collected about my sleep patterns after observing myself some months back.
So, used alarm and woke up at 11:39am today. Tomorrow same thing, but will nap in the afternoon for 20min.
Edit: It's way past midnight, I didn't keep my word about offing tech 3hours before bed. I forgot I'm doing this for no reason; just to find out how it feels.
