weird reaction to salbutamol

I have just needed to take a lot of salbutamol- more than usuall (about 4-6 puffs) and I have noticed that although i feel better, I have a very quiet wheeze/funny feeling in my chest, upon INHALATION. i say wheeze cause it feels that way but you can barely hear it. it is not stridor because it is deep down inside my chest... its very strange. anyone else get this?

Sometimes my chest wheezes play a little tune, usually after I`ve smoked a cigarette. Sometimes when I`m sucking in on the inhaler I swallow a bit of air in a panic which can give that sort of feeling in the chest.
