Suggest Treatment For Indigestion And Foul-smelling Stools

i have never had problem with eating any food and amount. For the past week after eating a meal of salmon asparagus, rice, red wine chocolate mousse, bread t restaurant, I had nausea and smelly soft stools. I ate a lot that day It was mother s day. I also had more alcohol than normal. I don t usually drink. Maybe a little wine here or there and a couple of sips once in a while to help me sleep. But I have had smelly gasfor a week after every meal and indigestion, with a mild back ache at my left shoulder blade.
