Hello and welcome to healthcare magic!!!
looks like your post drinks nausea just got worse because of your again irritating the stomach with extra doses of energy drinks with caffeine. Alcohol in excess irritates the gastric mucosa
which leads to nausea and vomiting
to add to the insult you have had energy drinks with caffeine which is equally irritant to the stomach i would advise you take a proton pump
inhibitor like Pantoprazole
or esmoprazole 40 mg half an hour before food one daily, avoid energy drinks,alcohol coffee or tea for a while,drink lots of water and fresh fruit juices.
