I did once.... first time drinking, drank a bottle of vodka mixed with OJ... started in a hot tub, BAD IDEA.. I didn't feel any effects of it, thats where 2/3 of th ebottle went.. then I get up to go inside, and about fall over, make it to the couch inside, finish the rest... remember barely being able to sit up straight... not really having full control of my muscles.... getting up stairs and into bed... then 2 PM the next day... I woke up with a hell of a headache... never again
