I've had what I'm about to describe happen to me over the past 5 years it seems. It always happens when I'm drinking a beer; sometimes I start choking after taking a drink and I end up having someone give me the heimlich; I recover right away like nothing happened. It's really starting to scare me now and wondering if I should just be using a straw instead. Not sure how cool that looks drinking a beer, but I'd rather live than die by choking on a beer haha.
