Glad to hear I'm not alone.
Loved it better when I was a med student and dating my wife. Now I make over $300k a year, have a big house, fancy stuff, fancy vacations but life is somewhat empty.
I long for the simpler days. Don't get me wrong. I love my little kids. But I do long the days of going back to a small shitty apartment, drunk and having some wild ass sex...
Breast feeding and co-sleeping ruined it.
Another thing. Studies have shown that men who co-sleep with their children have lower testosterone levels. I can vouch for that. I don't feel the same as I used to or it just may be I'm getting older.
