I found the question pretty vague...do you mean how much time spent doing neb treatments? or how much time do we spend on our CF care/treatment overall. I included the time it takes me to wash and sterilize my nebs, how long it takes to count out and take pills, the time spent preparing extra meals...If you add in everything we really have to do to take care of ourselves, I think most people would say more than 3 hours.
