As I am approaching Brians "league" (10+ dx'd), I felt compelled to contribute my 2 cents worth...I totally agree morning "on" is different from drug induced "on". I can stretch mine for several hours (adequate, not perfect functioning), walk for about 2 miles, exercise, even drive short distances. Nap during the day has not even a trace from this sleep benfit. Also I might add none of my neurologists have been very interested in it! Lisa Millen 56/10
