It IS very unpleasant! The throat closes and simply throws a temper tantrum like a child who doesn't want its nap. My sympathies to you as I know you'd both like to be able to do it. However AWFUL it might be, it certainly is effective. (On the other hand....maybe your sympathies to US, cause we're not quite fortunate enough to actually HURL - just FEEL like it!)
Enjoy your tea - and if the tea is working, consider yourself blessed!!
