You are correct. I should have been less definitive. I guess I'd better rethink diagnosing anyone else on the Internet. My primary reason for posting was to whine. I'm not proud of it but that's the truth. My secondary reason was to say, don't feel invincible as I usually do because you got the shot or never get sick. The shot is not a sure thing and you should still take precautions.
How that parlayed into me attaching flu shots or the healthcare industry I do not know.
Really? You don't understand the capacity for any forum thread to be derailed and sent way off track? And trust me, it isn't just OSA. I'm also on three different RV forums and the same thing happens there. Someone can take a single short sentence from a 5 paragraph rant on one subject and totally take it way off track.
Oh, and I hate to say it, but I can do that almost as well as anyone else out there on forums.
