Update:
Sincere THANK YOU to all who have replied (even those with smart a$$ remarks about my condition

)...
Sunday morning and I feel like a human being again. I think I will eat today; first time since Wednesday night for that to happen. I don't have a scale, but looking in the mirror, I don't recognize my face. I'm not a big guy to begin with, but the Wife says I've lost 15 pounds. Doc says some sort of acute stomach flu. I say super-duper asian death flu.
There is no possible way that I could have legally, safely flown today for my scheduled four day trip. However, there is a God, and he/she works in mysterious ways: my trip was taken for training and I'm off until next week.
In retrospect, I probably was a little scared by the letter on my attendance. However, the last sentence of "Failure to correct your absenteeism could, ultimatetly, result in the termination of your employment by ASA" did rattle me. I'm doing what I want for a living, getting fired by my first airline would not be a career enhancement move.
I was absent (genuinely sick) in July '07, Nov '07, and Jan '08, more frequent than average for me, but all three valid, actually sick, can't come to work kind of days.
The most frustrating part of this situation for me has been the fact that the occurence that pushed me over the top for a VFR-direct, one way, no expenses paid trip to the chief pilot's office was due the schedule that I was assigned to fly that week.
(To recap, I had four twelve hour duty-day daylines back to back. The third day IROP'ed into a 15 hour marathon. [Average half an hour from the time I stand at the bus-stop until I leave the parking lot, plus a 45 minute, no-traffic, that is, commute to the house, over four days, means that I'm getting 6 hours of sleep a night, if everything goes as planned. It didn't.] Called scheduling and asked them very politely to drop the first two legs of the last day. I wasn't trying to get out of the whole day, I just wanted to sleep so that I could feel like a human being again. Instead, when they decided that they would reduce the in-domicile rest to 9 hours when IROP was declared so that I could legally, conratctually duty in on time, I called 'fatigued'. I called the Chief Pilot on duty, received a tense lecture on 'the rules', and was relieved, without pay[Which I'm okay with; Take the pay, but the occurence for 'fatigue' is Bravo Sierra.], from my entire trip the next day.)
IF, God forbid, I would have made any mistake on the fourth day that would have either bent metal or broken bones, I strongly suspect that I would have lost my certificate and job for not calling in fatigued, per the FARs. In doing the right thing, calling in fatigued, I feel like I jeopardized my job due to circumstances beyond my control.
I'm very appreciative of the opportunity that my company has given me to date. However, instances like this do not make me want to 'go the extra mile' for my company.
Anyways, thanks again for the folks who contacted me to wish me well over the last few days. For Y'all I will go the extra mile, or two, if necessary.
