Over dose?????????///?

okay so i took probably around 4 table spoons of night time equate (Equate Nite Time Cherry Flavor) . Now that's about double the dosage that your suppose to take ( 2 table spoons every 6 hours) but it doesn't exceed the 4 doses per 24 hours......i too 2 doses in 24 hours just all at once now i know this was stupid i was at a party i had a drink or 2 (wine) and when i went home i didn't feel good and wanted to sleep so i figured itd knock me out (it did :p) now that was Saturday night its tuesday and Im sick [i just got sick it hasnt been since saterday or anything] ( diarrhea and vomiting) but i hope this has nothing to do with the equate and is just a stomach bug ( i throw up a lot and getdiarrhear a lot i have a weak stomach) Im a boy Im almost 5 foot 11 and im around 190 pounds so pretty much my question is should i be worried about dieing haha like is my liver going to shut down because i know equate is like nyquil and is antihistamine i dont want any answers saying u should go to the doctor or any of that i want a straight answer from some one who really knows i don't want opinions i want a nurse or doctor or some one who has knowledge of this to answer am i okay or should i be worried?
