You drink wine every night?
My schedule is far too buy to allow that...perhaps that is part of it? You are in a relaxed enough schedule to have some shutdown time every day?
I have a pretty busy schedule but a while back I started adjusting it to allow for time to actually sit down and eat a real dinner. My wife and I usually have 1 glass of wine each. It's a great way to reduce stress and enjoy life. It also helps me get out of the twitchy, burnt out feeling after writing code and drinking tea/coffee for 10 hours.
I go to bed about 3 AM, and there's not much pressing business after midnight.
Pouring a glass takes what, a minute?
True, but I find my ability to code significantly diminished after even one glass. I'm all for finding some time to unwind with a glass when you can, however...
My quality of work would suffer for those few hours, I wouldn't be able to go at 100%.
