Vomiting bile/Do I need to go to the ER?

Hi, okay so I'm not a heavy drinker but I drink consistently. Last Wednesday morning I woke up and got feverish and cold sweats and starting to puke bile first thing in the morning. It followed with a bout of laryngitis and a sinus infection for 5 days. Last night I drank four shots of rum total in four rum and cokes and I am absolutely ill today and puking stomach acid. If I start puking bile I'm considering going to the ER. Is this too rash? What's going on? Does my liver want to resign?
