Stuttering
Equus,
I can really empathise with your husband. If it makes him feel any better tell him that not only do I stutter but in tense situations I get very nauseated and many times have barely made it to the bathroom in time! During exams when I was in university - I had a special place at the back of the hall with a bucket next to me - I didn't have to worry about anyone cheating off me - people would get to the exam extra early so they wouldn't have to sit near me!
Also had to interrupt my own wedding to do the 6 second bathroom dash. But then, he is my ex now - so maybe that just was my body trying to tell me something!
People have suggested to me to take a public speaking course (such as a Dale Carnegie series) - just thinking about it makes my stomach knot! Too bad you guys live in the UK - or I'd offer to go with your husband.
Tell him my thoughts are with him.
