I am 77, recently diagnosed with COPD and was never on any medications. I never smoked but exposed continually by spouse for decades. I am grateful for my former health but having a most difficult time having to focus on 'me.' I don't like meds, especially steroids, but read that meds are essential for life span with COPD. Never even been to a hospital. Tried the SALT booth yesterday and it helped a lot. Anyone used this treatment over a long term. It costs $7K but has an easy set up.
