@sweethighland Maybe it's your dose that's making you shaky? After you use it a bit your body might be get used to it.

At first I used Levalbuterol 1.25mg via nebulizer, which made me very nervous and anxious for hours. It seemed impossible to settle. Once I tried Levalbuterol 0.63mg (half of the prior dose) it was much better, very little if any noticeable shaking and the benefit of clear airways.
