smoking cigarettes alot can definitely worsen your breathing
citerizine is zyrtec allergy medication and should not affect your breathing. and should help with your allergies symptoms.
have you tried to quit smoking before?
yes. i only started smoking a lot of recent
i was stopped and breathlyzed and the equipment the police used wasn't picking up my breath despite the fact that i blew into it as hard as i could
sometimes summer can worsen allergies as well.
you could be having some asthma associated with your allergies.
you need a pulmonary function test to see if using a bronchodilator will help open up your airways.
you might need a bronchodilator like albuterol to help open up your airways so you can breath better.
but you also need to cut down on your smoking
does this help
do you have other questions?
