Yes! I was sore and dehydrated for awhile too. I think it's great that you are not dealing with anyone unless absolutely necessary. I didn't even answer the door for the first couple weeks. I didn't care who it was; I wasn't going to deal with it. "It's ME time".
I guess it varies as to how long it lasts. Depends on the person, how much you were drinking/using, etc etc. But it all means that you are healing and that is GOOD!!
Keep going! You can do this.
