Choking

Husband is having more and more troubles with coughing mainly after drinking, not so much after eating.

Last night while relaxing and watching telly, he took a sip of whisky and then had the most scary 10 minutes of coughing and choking. Kept saying something is stuck and he could not breathe! He was only drinking and not eating at the time.

Any tips on how to overcome such an episode as we were very close to ring for ambulance!
