Question about pill.

I’m going to be getting the ab pill on Tuesday afternoon. I’m super nervous, of course. I’ve read all about what will happen.. what I’m wondering is.. when should I go back to work? Right now I have to work on Wednesday afternoon but will I still be having the effects? I’d like to know now so I can get myself coverage if I’m going to be out.. I assume everyone is a little different, but what were some of your experiences as far as when you were feeling better?
