Like your husband, I have chewed tobacco for 50 years, quit for a short time, go nuts, temper tantrums, can’t sleep, think, back to the chew! I can’t say it has affected my lungs, mine all started with blood clots in my lungs, leading to pneumonia. Then my wife of 42 years walked out to join a ——- religion. Stress, living alone, I never was depressed, just mad at myself and anything that pertains to getting better! Family stress, Drs. moving, causing breaking in a new Dr., it just wasn’t an enjoyable affair. I am chewing tobacco again right now, ENT evaluated me recently, said my mouth looked fine! Back issues, knees need replaced, old body worn out. But I want to spend more time here, enjoy my Grandchildren, family, hobbies! Yes, I would like to hear of anything that will help me breath easier, have less discomfort in my feet. .I hope to hear of new treatments that will relieve, cure, my problems.
