My father has a lung function of 47%. For the past 2 weeks he's been cutting back on the smoking going from 3 packs/day down to a little less than 1 pack/day. I just can't seem to get him to try to quit all together. Any advice? I know for some it takes a while to quit. I bought the Nicotine lozenges he said they taste terrible and make his stomach upset. He has patches but doesn't leave them on long always taking them off and going for a smoke. I was wondering do nerve pills help with the anxiety of stopping? Would that help? What helps a person quit?
