Are Diarrhea And Vomiting Withdrawal Symptoms Of Vicotin?

my wife overdosed on vicotin 10/325 twice in 6 days. The first time it knocked her out for 2 and a half days. She then recovered for one day and the overdosed again and it knocked her out for another 2 days. I then found all her vicotin and took it all. She was not a daily user of vicotin prior to the overdose, it was just a one time thing. Is it possible she is withdrawling, because she is experiancing: diarrhea, sever anxiousness, sever lack of appetite, can't find a comfortable position and rocks her body back-n-forth while lying on the bed.
