sorry for all the threads but, I just have one more question.. is Ventolin okay for your heart if you don't get tachardia or palpitations? I got slight pounding for a second or two when I had 4 puffs after my methacholine challange to bring me back to normal but, today when I had two I didn't notice anything, and no shakes.

Does that mean it doesn't affect me that way? Is it safe for my heart?

4 puffs is a lot....and not what they recommend you do on your own. One or two when having an attack is normal. So, if it didn;t bother you at that level, you'll be fine. Just don'e OD on it.
