Sorry, that was my fault. Perhaps if FlyerTalk used 4-digit years and and a more intuitive DMY or YMD date format, I might have noticed that the thread wasn't 1 week old but 5 years 1 week old!
Nothing to apologise for. Old threads over two years dead are normally allowed to slip away peacefully but where, like your posting here, the resurrection usefully contributes adds and explains up-to-date information on the topic which people will find on a search for CPAP use then it continues to be of value to the general good of the board.
