I rarely drink, and when i do it's usually only 1 or 2. i went out and had 5 which is highly unusual for me. i got sick. it's been 3 full days and still feel nauseous, should i be concerned? i've been forcing myself to eat and i can barely stomach it?

Although you may still feel the effects of the excess alcohol intake, if the nausea persists in the next day or two, see your primary care physician for an exam and other testing.

If your symptoms are due to the alcohol, that’s one vicious hangover from five drinks. You can try antacids such as Mylanta orTums to see if it calms your stomach down. Drink plenty of (non-alcoholic) fluids. you should start seeing improvement within a day or two. If your symptoms persist, see your doctor. Good luck.
