I have heard more than plenty of people say that the "feeling better after diving nitrox" is just anecdotal, and I haven't seen any research, but I have experienced this when doing multiple dives a day for 2-3 days.
Weekend one - 3 dives a day for 3 days. Diving air. Absolutely exhausted.
Following weekend - 3 dives a day for 3 days, diving nitrox. Tired but not nearly as exhausted.
Conditions were just about the same, ocean boat dives, with mild current, 1-2ft chop.
There may be other factors involved, but since then I dive almost exclusively nitrox.
hydration plays a lot I have found, after installing a p-valve in the suit I started drinking plenty of water before the dive. I have found that I started feeling way better after the dives, no matter if they were on air or on nitrox
