Tip #1: Put some pants on.
If a waistband with a button feels like too much right now, go with a caftan & sneakers.
Tip #2: Pre-batch them cocktails.

Tip #3: 70s music.
On vinyl, through Alexa, by carrier pigeon. It doesn't matter how, just do it and you will thank us.
Tip #4: Cook something easy.
