Hello,
Sometimes after surfacing from a deep dive I will get what my diving buddy and I call the "Buzz"

The feeling is simular to the one you get when you stand up to fast, you kinda get dizzy and numb.
This cant be good

(even though it kinda feels good)
Is what we are experiencing a samba or the edge of a black out?
Is there any training or warm up's that can prevent this or am I just at the end of my current limits?
Thanks for the help,
Jay
