I’m diagnosed with moderately severe COPD. My main complaint is insomnia and chronic fatigue. At the moment, I’m taking Doxofylline tablet 200mg twice a day, but my doctor really advised me to use the nebulizer with salbutamol together with the Doxofylline tablet. My sleep has improved, but not much. I would like to try using the nebulizer without the tablet first, for the reason that, if possible, I don’t want to take too many medicines. I’m hesitant to start using the nebulizer because I know if I start using it, then I will always have to use it continuously.
