When I'm working from home, I get 64 oz about 80% of the time. I rarely get more than that. (Not including protein shakes or soup)
When I'm traveling, ugh, some days maybe 16 oz? Never more than 32 oz. I've given up, I don't even try to hit 64 oz. I mean, I can't carry a Yeti around with me all the time, bring it to customer meetings? I can't just stop in and buy bottled water all the time. Can't drink during or after meals.
I used to drink quite a bit on planes. But that bit me in the ass one time, so I'm hesitant. I really had to pee, but we had started our descent, so I held it, then on the ground we had to wait and wait for a gate, I was dying. I finally just got up and told the FA I was pregnant and couldn't hold it anymore. That was half true at least!
I get the most water in when I'm out at bars. But water is never refilled as quickly as alcohol, so that slows me down. It's funny, four pints of beer is 64 oz, and that was no problem what so ever, just getting started for the evening. Four pints of water feels like an impossible task
