It sounds like you had a bad reaction to the
alcohol,
and having drank some more, you started to experience it briefly. Try not
drinking for a few days and see if this goes away. Green stool means it passed too quickly thru your system. Also, re-hydrate after vomiting and diarrhea, by drinking water, orange juice, and Gatorade plus you can eat bananas to replenish your electrolytes.
