I believe I feel better, therefore I do.
But the real advantage comes at the end of a 5 dive day.

Um ... the wife just told me to mention that she'd much rather I dive EAN.
So does that mean that EAN has a Viagra effect
Sorry Thal, but I just couldn't pass that one up

It means that I did not have to go back to the room right after supper and instantly fall asleep.
Honestly, I haven't done a dive on air in so long, I'm no longer sure. But I'm quite convinced that, when I switched, I was sure it reduced my fatigue. But I also changed my ascent procedures at the same time.
I did have a personal experience that convinced me, beyond any argument (or facts), that subclinical DCS is manifested by fatigue. I did too many ascent drills in one night dive, some of them rather poorly controlled, and at 7 pm I was driving home like I was sedated. Stopping at a light, I'd nod off before it changed. The only time in my life I have ever felt like that was during residency, when I'd be up 48 or more hours.
I don't do multiple ascents in a training dive any more.

Hard to know for sure, but 5 dives a day in warm water 30% and I feel great at the end of the day. One dive on air up here and I am bagged, lots more work and the cold takes it out of you but I think there is more to it. The only liveaboard in warm water I did with air (prior to getting certified for nitrox) I was skipping dives I was so tired.
Don't normally dive EAN for a single tank dive, but I guess I'm just going to have to try it out and see if it makes a difference.

Whenever I've had classes with lots of students and end up doing lots and lots of ascents I try to do them on the first dive of the morning and I make sure we're doing them fairly shallow for exactly the same reasons as you. Especially with students you may find yourself ascending a bit quicker than you yourself would on your own. So, early and not from much depth

I know the "experts" say that there is no evidence for the effect, but personally, I feel noticeably less tired after repetitive dives if I'm using Nitrox.
I use nitrox when conducting checkouts with students. 5 or more dives a day and I notice the difference. When just putzing around and not going deeper than 100 feet. Air is fine. Deeper than that and I add a little helium into the mix as well as up the O2. Less fatigue, clearer head, no headaches afterwards, and, like Lynne, I'm not nodding off on the way home.
