I have never met anyone else who does this, my fiance can't sip or drink anything over time.
Every cup of coffee, tea, glass of water or coke, he holds and drinks in one, continual cycle of gulp to swallow, maybe pausing to take a breath halfway through, but not always. He then slams the empty cup down like thor.
AIBU that the normal way to drink most drinks is to have a sip or two and set it aside?
I have tried it myself and it results in hiccups or drowning.
