i didn't want to say anything really, but Skully helped me,,, i actually believe that Sanity Test is really a Skills Test... but before i got on oxygen i was 106 and after i had been on it a while, and was CPAP'd and sleeping right, my score came down to 45.... did i suddenly become sane ? i think not,, i suddenly was better able to function,,, oooh well,,, Gus
