Thinking about medicines. They are all drugs. Many have to be 'carried' to the point of efficacy using inactive stuff. Now I only drink wine but I give my liver a rest every week - 1-3 days alcohol free days. Here's the thing - we COPD sufferers inhale a significant amount every day. Some is active and goes into the blood stream, loading liver and kidneys of course; but some is not but carries the active to destination. What remains must, well remain. Does it help or hinder our breathing? Could we benefit from a day off every week?
Any experts out there willing to think outside the thorax?
