No but whenever I’m at NIH and they have me inhale the stuff I think it’s a lot stronger because after 3 or 4 breadths I go into a bronchial spasm. You have to watch that. They probably give you 4% instead of 2 or 3%. I swear 1/2 of them don’t know what the heck they are doing. I had to tell THEM why I had a spasm. After you get your prescription and find that it works bring a vial with you when you have to give a sample at the hospital. That’s what I do now to be sure they aren’t going to give me something way to strong.
