Just curious. I have noticed for myself that there is a period that lasts approx 72 hours after diving during which I am really eager to do more. Of course, I always would prefer to be diving than sitting at my desk at work or doing many of the other things that I do in life, but the need to go diving somehow seems different and more intense for a short period of time after a recent bout of dives. I suppose it is just psychological, but it doesn't seem outside the realm of possibility that subtle neural efx of diving relating to nitrogen, for example, might actually result in some form of low-level short-lasting addiction. Has anyone else experienced this or head any discussion of this topic before?
