You know, people don't adequately prepare the young honeymooners for that.
When you're newly in love and talking about marriage and drooling over each other, you always say stupid things like "we want to have 10 kids in the first 10 years!" And that's when we older folk should pounce! 
That's when we could really do them the service of just terrifying the living crud out of them. I mean, really do Bill Gates a favor and scare them right into never reproducing.
All you would have to do is well and efficiently explain that you'll stop drinking to be a better parent, (and because you never have adult time without being in charge of someone else's survival), but the hangovers will somehow continue for the next decade. 
You'll wake up every morning with cotton mouth and a headache and eyes that feel like they have glass in them, and feeling like you have been kicked by a tiny mule all night long, likely because that's not far from what happened. 
They never stay out of your bed! In fact, you never get any privacy at all. Want to pick your own nose, maybe rub it on their wall? You can't, they'll be right there, watching you. Even if they were upstairs at Grandma's eating fresh baked cookies the moment before that, they'll be right there, looming, silent for once in their lives, just catching your immature revenge-parenting behind!
I know you caught that little nugget in there. Yes, we live with my mom. I'm not only destined to always be caught out in my immature revenge-parenting but I live under a real life cookie baking Grandma lady who had about 40 years more parenting experience than me and a straight up license to still call me onto the carpet for the weird stuff I do.
My kids tattle on me more than they tattle on each other these days.
