That's my current level of hell.
Just a word of caution to you guys doing this stuff for fun (this next part is for the OP):
The other night I had to hand fly a non-precision approach to mins in the rain in the mountains after 15.5 hours of duty. When we (I'm including my 8 passengers ignorant of their impending doom) got on the ground, well, it took a minute or two to get my hands to stop shaking enough to write in the logbook. I've shot that same approach in similar conditions many many times, but the combination of weather, night time, and fatigue pushed me right up to the ragged edge of my ability level. I'm no super pilot myself, but I'm an ATP who does this single-pilot IFR thing for a living, have about 600 hours in the aircraft type in question, and fly out of that particular airport on a daily basis.
If you're not careful, this stuff can bite you when you least expect it, even if you're normally feeling comfortable. Set personal minimums and stick with them.
Fly safe!
