Ha, I have had similar experiences when drinking moonshine.
Hint: Always drink shine standing up. If you sit in one place and drink large amounts of it, it has the rather unique quality of fooling you into thinking that you are still pretty clear headed, that is until you stand up. Then you realize you have lost almost all useful motor control. The clear headed piece goes almost immediately after falling down and thus quickening your heart rate.
ie. same thing with sake. The first time I drank warm sake in a tea house, I stood up and fell over.
