That&#x27;s a good question. My social life is mostly daily (e.g. rock climbing etc). I don&#x27;t drink alcohol, I don&#x27;t go to bars&#x2F;nightclubs.<p>But sometimes I have to brake my sleep schedule.<p>For example, two weeks ago I had to fly to another country for a job interview. Unfortunately, I had no better flights, so I had to go to the airport at late evening.<p>I finally got home (from airport) at 3 am.<p>I felt very tired during next 4 days.<p>My sleep schedule was:<p>Day 1: 3:30 am - 8:30 am<p>Day 2,3,4: 21:30 - 06:00 (applied sleep restriction!)<p>If I didn&#x27;t apply sleep restriction in the following days I would mess up my sleep at lest next two weeks.<p>In my case, one night with broken sleep schedule costs me 4 days.<p>I think it&#x27;s possible to brake your sleep schedule once in 3 weeks but if you do it frequently it would be bad for your sleep hygiene.<p>So frequent alcohol and night-life is not compatible with healthy life style (at least for me, it&#x27;s 100% truth).<p>So it&#x27;s probably question of priorities.
