Started biphasic sleeping today.
I fell asleep around 1:20am (the plan was to sleep at 0am but couldnt sleep) and woke up at 6am
I felt great until like 10am then started feeling a bit tired and now its 11am and im a bit better though not as much as if i slept as i normally used to (from 3am to 11am).
I wont take the 90 minutes nap today because i want to be able to sleep as soon as i go to bed.
I hope the bit of drowsiness i feel now go off once i get used to biphasic sleeping. Did you guys also have some drowsiness in the beggining?
