Effects of Drinking a Fifth of Vodka?

I am 5'7, 130 lbs, and on Saturday night (three nights ago), I drank a fifth of Burnett's. I felt fine the next day, and then Monday I finally got the hangover and wasn't able to get out of bed. Today, I've been experiencing diarrhea and was wondering if this, as well as my sickness Monday, were still effects of the drinking.
