Anyone else been hungover for 3 days?

F29 and I hit the whiskey haaaaaaard on Saturday night. I don’t drink much to begin with and was sober for 2 years because starting to casually drink again in September. I had a get together with family on Saturday and we had a LOT of whiskey. The next day I was nauseous and tired, no appetite, but that finally cleared around 7 pm. Yesterday though, I woke up nauseous as hell again and didn’t have much of an appetite until around 4 pm. This morning, same thing. Super nauseous, stomach feels full of battery acid, and I feel shaky. I’ve been drinking tons and tons of water (2-3L a day) and keeping the salt intake up. But it’s been 48 hours and I still feel like death. I’ve only puked once, and that was first thing Sunday morning
