Sorry I was out most of the day.
Lortab and Vicodin are the same medication = Hydrocodone.
Hydrocodone comes in 5/500mg and 7.5/500mg. You could ask your Dr for the 5/500mg or break your 7.5/500mgin half = 3.75/250mg.
The medications is pretty strong for some people and on top of your meal the whole episode just did not work well. We all do the same things so I hope you are feeling better by now.
