I drank last night. I had three vodka and red bulls at the club and prior I had a rum and coke and 2 Smirnoff ice drinks. This is normal intake for me when I go out (about once a week or every two weeks) and I rarely get more than tipsy and rarely hungover. Last night, It made me super nauseous, dizzy and then I had these hard core chills that lasted through a hot bath and bundling under all my blankets until I passed out. What caused that?
