Water weight vs fat weight after a 4 day binge

Kimblesnbits

Long story short, I went to Vegas for 4 days and ate/drank like crap every single of those days. I came home monday and knew I've gained lbs because I can see it and feel it in my clothes so I didn't wanna step on the scale. I'm curious how I could find out how much of that is fat lbs vs water lbs. How long would you wait to weigh yourself after, lets call it a 4 day straight binge to be safe! Also, from your experiences, how long would/did it take you to lose temporary binge weight?
