Poor Hess, we've ALL been there. God, your evening sounds like pretty much every wednesday night I had from 2006-2009. And no, I'm not kidding (why wednesday? it was trivia at my local bar and then karaoke at this club my friends and i liked...needless to say we all did have school or work on thursdays though!). Anyways, there was a time when these crazy long random nights felt exciting, fun, not that absurd. Now as you say....we can't keep doing this ****!!!
"I was drinking for about 15 hours, so this is clearly an example of "drinking through the Nal." While we were watching the Super Bowl, I really struggled to put beers down (and had I been at home, I probably would've stopped drinking altogther and just passed out...I felt completely miserable). In order to get myself through the game, I switched to whiskey which pretty much guaranteed a sh*tshow"
Yes, in a nutsheel you've identified your own problem lol. This is exactly what happens to me too.
Hess, it will get better. You just might have to do a few things to help it along, I think. 1) one 50mg pill is not going to cover you for 15 hours. You know that. Bring an extra pill or even better don't sign yourself up for 15 hr drinking sessions

2)try and stick to the beer if alcohol is what makes the shitshow come to town. 3) maybe try exerting a modicum of willpower? Like setting limits before you start drinking and trying to keep to them? Just some thoughts, Hang in there Hess, we're all rooting for you!
