Yeah, if there's one lesson I'd like to pass along to everyone trying to lose weight: if you screw up and go on a binge for a couple days, your weight may spike by like 5 pounds or even more. DO NOT PANIC and then chuck in the towel. There's essentially no way to gain that much "real" weight in that short of time frame. It's mostly gonna be water and it comes off just as fast if you hop back on track. 182 became 174.5 in less than a week. It gets a little harder from here obviously.
A slipup/binge doesn't really sabotage your progress as much as it actually just stalls it for a bit. Not great, obviously, but not the end of the world.
