Thanks DuncanUK, didn`t see your post til just now. I didn`t think it was a big deal, but the docs here in Mexico have a very different view of things than the docs in the US. IE no malpractice settlments to worry about and generally don`t make things sound as dire as US docs. Take it seriously yes, but decreasing the effectiveness by 10 percent seems a little extreme to me, sorry Davesc, especially since I didn`t go the whole 24 hours without. Thanks to all.
