Absolutely. I worked on a team where the lead engineer would be out of the office for weeks at at time, and then when he'd return he'd skim in-progress code and request radical revisions, only to criticize those decisions the next time he was in the office.
I was actively looking for a new job when he quit, and it was such a relief. My productivity (and happiness) went through the roof, and a couple months into the year my manager told me that I'd already accomplished everything he hoped I'd accomplish _for the year_.
By exchanging a some technical skill for a better work environment our whole team benefitted.
I was in the same position for most of my twenties. I did well at work, was in (mostly) good physical shape, and didn’t have any trouble rehearsing/gigging with my band. I really thought I just “liked to go out;” I’d drink when I had band practice or a gig (2-3 nights a week), then would go out on Friday and Saturday nights with my friends. That only left two nights a week to hang out with my girlfriend, so of course we’d go out to dinner or make something to eat at home and end up at a bar.
I honestly didn’t understand what denial was until I woke up one morning and realized I was an alcoholic. I quit drinking 6 years ago and could not be happier with my decision.
I've heard multiple accounts of him seeing a WIP and asking for changes that compromise the product's MVP.
