Thank you

I talked to the Wei company. It seems to be a very expensive vitamin co. They said the first level was I think.
$5000. They gave me the name of a Dr. but she was losing her office and did not know w here she would be moving. My primary Dr. Said it was a company selling expensive drugs. Hope this helped

No, have not heard of that company...... I did not know there was a stage 5........thought stage 4 was end stage for COPD.....On the other hand I do not pay attention to numbers......I live a day at a time and take as good care of myself as I can with rest, good diet and exercise and live life to it's fullest........
