The last week my airways have been tight so I have increased my albeuterol nebs from 2 to 3 times a day. I have found that the usual 1 unit dose doesnt quite seem to be enough to really open me up sufficiently. I know that we are not suppose to double & would imagine that I dont need THAT much extra. I was just wondering if anyone else notices during harder times that the normal dose is a bit shy of what gives them the full benefit?
