I usually easily wake up with first&#x2F;second alarm at 6:00&#x2F;6:01 and feel fresh.<p>Sometimes, I feel sleepy at 06:00 but since I clearly got idea of &quot;sleep restriction&quot; into my mind, I actually inverted my emotions about wake up time.<p>I mean I actually worry if I spend in bed later than 6:03 because I know very well that it&#x27;s costly to break my sleep schedule.<p>One day I actually missed my alarm clock because my phone was out of charge.<p>Since my room is completely dark, I woke up at 7:20 confused about time and with headache (i.e. headache after unusually long deep sleep).<p>Next 4 days I felt tired and my sleep wasn&#x27;t very good.<p>So now, I double check my alarm clock and my phone always charged every evening :)<p>I.e. most of the time it&#x27;s easy to wake up at 6:00.
When it&#x27;s not easy, I wake up anyway since I get a lot of negative emotions if I brake sleep restriction principle :)
