Sorry my english isn't very good, what's fsw?

The problem with simple studies is that they may not be checking in the correct area or the right things.
However, there is a big difference between "feeling better" or less fatigued and what you seem to be discribing.
We do know of several things that might cause one to be very tired after a dive, a few of which are:
1. Blood sugar levels...
2. Hyperventilation (and a whole variety of similar issues from high CO2 retention to low CO2 retention)...
3. Have a PFO
4. Be more susceptible to DCS. Remember a small percentage of the human population will have DCS issues, even when they follow the tables.
If you are doing deco diving, then you will have some level of micro bubbles in your system... how your body will react to that varies trememdously..
The problem is, no one on the internet would be able to answer why..and the possiblities vary from trivial to pretty important..
I'm all for looking at evidence-based diving practices...but it's pretty difficult (and almost certainly incorrect) to argue that nitrogen loading does not affect a diver's post-dive fatigue level.
I think idocsteve's comments are misleading. To clarify, there is no conclusive evidence to support that using a 32% nitrox mix significantly decreases post-dive fatigue when compared to a regular compressed air mix. It is flat out wrong to take this previous statement/conclusion and hold it up as evidence that nitrogen has no bearing at all on post-dive fatigue.
Because it seems, to me, that you're saying increased Nitrogen absorption equates to increased fatigue, and then it would follow (please correct me if I'm wrong), that diving Nitrox as compared to air would result in less fatigue, all other factors being equal.

@idocsteve: Please pay attention to the qualifying language in my posts. "...pretty difficult (and almost certainly incorrect)..." was purposefully inserted into my statement.You say it's incorrect to argue that nitrogen loading does not affect a diver's post dive fatigue level, which is a double negative that can be simplified to:
"Nitrogen loading increases a diver's post dive fatigue level."
Show me a study that conclusively proves that.
@idocsteve: Please pay attention to the qualifying language in my posts. "...pretty difficult (and almost certainly incorrect)..." was purposefully inserted into my statement.
This appears to be subjective. However, my experience is that if you're doing more than 2 dives in 1 day, nitrox will keep me from getting fatigued by the 4th or 5th dive.
