I must agree, this winter is worse for me too. Nevertheless it is nothing in comparison with you and your problems. I am still happy with Ventolin, only I sometimes wake up at night wheezing but one dose works nicely for me. Again - sometimes it happens, sometimes not and I have no cue why.
Also laughing too hard leaves me wheezing and coughing.Normally I am a giggler... it has been very rare recently but I am still the same person:-)
So far, the only perfume that has made me sneeze but not wheeze, is my lady boss´ sweet and heavy one.
