young man, don't you listen to the ads? Ceye-alis gives you up to 36 hrs to serve dinner (wink wink, nod nod) and has the warning of a 4 hour construction problem (if you know what I mean)
why would anyone use the purple pill?
not that I or anyone I know has ever used one!!!!
Disclaimer: Neither I nor my Blind Trust own stock in the companies that market Veye-agra or Ceye-alis.
(Note: the mere mention of the above medications gave me a stern warning by the new "naughty language" filter)
