Thank you, Michael. I haven't noticed any of those effects from it with Rog and our doctor is monitoring him carefully. What I have noticed is he is not waking up every morning hacking his lungs up from congestion from smoking.

Just checked with him. He hasn't noticed anything except that it kind of *kills* the pleasure receptors, as he put it. As a consequence, he is not drinking as much, either, which I had noticed. Drinking was not a problem, just a glass or two of wine or a couple of beers in the evenings, but it won't hurt his semi-beer gut, either.:-)

I will definitely look over those links. Thank you for posting them.
