Has this affected anyone in the oil field? Thanks. 

Plan ahead. Hydrate, and sleep before you fly. If you are worn out before you travel, it's all down hill from there.

the best advice.  Commuted overseas on my own dime for a long time, did what you said.

 no, never in the history of mankind has jet lag ever affected anyone doing hitches in the oil patch. 

i commute from another country

California. 

I used to live offshore for my hitch. A young pilot once asked me, in all seriousnes, "What happens if you wake up in the morning and you're sick?" I laughed and said you get up, put your pants on and you go fly. There were no spare pilots that could be sent out to cover my job while I slept or watched movies in the tv room with a comforting cup of hot tea. You man-up, you take whatever meds you need to take (approved or not), and you do the friggin' job. If you're worried about jet-lag, you're probably in the wrong business.

Stay home if you're sick. Ignorant rat. I don't wanna catch it and take it home. 

Real manliness lies in wisdom, fortitude, judgement and faith. 

there was always spare pilots and aircraft for breakdowns offshore or whatever. if you say there wasn't, you didn't work out there. I worked at three different companies over 10 years.

moons ago I did 10 years with the tea bags, offshore.  Pretty much the same unless very deep in the boonies.

There were spare pilots at some bases, not all. THese were generally newer pilots who did not meet the minimum requirements of the oil company I flew for. There was no job description book with a diagram of the platforms in my field. What was this guy going to do, fly out and do my job while I watched tv? Give me a break, that's not reality. In all the time I worked in the GOM (15 years), I never heard of a single offshore-based pilot "calling in sick" during his hitch. We were adults, not children. You got up, put your uniform on, and did your GD job.

 "What was this guy going to do, fly out and do my job while I watched tv?"

Yes. That's what sick time is for bro. It's just the oil field.

wussified version of "manliness".  Others will get the job done, you just go on and take care of your sniffles there Nancy. 

you just said nobody else would come out and do the big important job of flying the rig apes around. you gotta make up your mind bro. remember when they used to stick the newbs and old losers that everybody else ran off on the offshore jobs? good times
