It's not overanalysis. The fact that drinking and losing sleep is physically unhealthy, along with the fact that there's widespread social pressure to partake, means that the question is worth exploring. You don't have to agree with the answer, but your dismissive and defensive attitude is exactly why a study like this is worthwhile. If you aren't someone who prefers not to drink, you probably don't really understand where the pressure comes from. Every single time you go out with new people, people make comments on your lack of drinking. Either the fact that you ordered a 7-up or that it's been 3 hours and you still haven't finished your first beer. Plus the bar itself is designed to sell alcohol, so there's inherent pressure just by being there. My primary career (IT) doesn't involve a lot of people going out drinking on a regular basis. But I sing for fun, and in that field people are constantly out late, and yes there is pressure to drink. EVERYONE who goes out drinks more than me, and even people I've known for a year or more still make comments. And lately I've had to skip the drinking night because I have to be up at 6:30 AM the next morning for a meeting. I feel much better physically and mentally but I'm socially out of touch. Plus, there's the matter of being at the bar when your regular bedtime passes and your melatonin starts kicking in. All the drinkers don't even notice and sit around yammering for another hour or four while you sit there yawning.
