Vicodin and Penicillin cocktail

I don't mind the antibiotics, except that having GERD creates more uneasiness in the stomach. While the infection is being wiped out so to speak, I've got Vicodin in generic form lingering in my system. The stuff has got me so numbed that sitting at work has become unbearable. My attention span is nill, and then I feel all giggly out of nowhere. Granted the pain is almost completely gone, I in the meantime have to sit at my desk like a zombie. Why can't there be Vicodin for the day time?
