MIxed Gas, Extra Dry

We arrived at the new job sight yesterday afternoon.  The working depth is at about 200'.  At this depth we have to breathe a helium oxygen mixed gas.  
The majority of my dives over the last 4 years have been mixed gas, so this is no new thing for me.  It's just that I haven't done a gas dive in nearly 8 months.  And it's always a little bit more...  how you say...  moths in stomach? 
But the dive went off fine.  Black as hell, in the mud, with zero visibility.  It was my first pipeline flange hookup.  A long piece of pipe that had to be connected to another piece of pipe--which sounds really simple--and yet somehow... you can never underestimate how difficult the simplest of tasks can become when they have to be done at 200' in a pitch black mud trench.
I got the drift pins stabbed through the bolt holes in the flange, and got one bolt hand tightened.  
Forward progress, movin forward, not regressing.  As long as you don't move the project backwards, it's a successful dive. 
And then it was on to 1.5 hours of in-water decompression, followed by 2 hours and 45 minutes in-chamber.  Finished half the book, "Master Butcher's Singing Club."
All in a days work.  Now I goto sleep at 4pm.
