Since a few days back I am taking far more ventolin than usual. (I am now also on prednisolone. ) Do other people find that using ventolin up to four times daily can affect sleep? My sleep has been poor e last few days (not helped by waking up from a noisy chest yesterday 4am, or from coughing today at 6am), but by now I feel I am getting gradually sleep deprived. And I am not enjoying that as it makes me sluggish. Also my current condition does not help me go for walks which often helps with my sleep. So, could this be the ventolin?
