I don't believe so, I am not a real 'panicky' sort of person
geez i know what you mean about the boa constrictor effect, years ago I had to go to a relative's funeral and I stayed at my aunt and uncle's place and my aunt and some other people smoked and smoked and smoked....all the windows were closed, and then I slept in that room!!! I woke up the next day like there was a pile of bricks on my chest, a weird pressure.... I complained about it but nobody listened to me. When I got home I went to the Dr, my lungs were clear and he told me to come back if it got worse, well a few days later I got bronchitis :/. I know for a fact I do not have Asthma but a 'sensitivity' to second-hand smoke (whatever that means?!) Also sometimes cold air makes me cough.
I'm fine now, I don't have that weird feeling, but I had it last night. Argh
