Quoted message said:I have just done an open water swim practice with my club. Also the furthest
single swim (1.5 mile) without pushing off from a pool side every 25m.
I really pushed it, done the lot, varied my breathing rhythm, practised
drafting performed some intervals. When I exited the water I felt drunk, the
floor was moving the lot. Why would this happen? If it happened in a race I
would probably fall off the bike in transition.
The water was cool but not cold and I was wearing a new Orca speedsuit which
felt good and warm, no swim hat and I felt warm leaving the water.
I also found out how badly I Zig Zag in a 'straight' line between buoys. I
was in a lake, in a swell Jeepers!

That's because so much of your blood has been drawn to the working
muscles in your arms/chest, AND you are going from horizontal to
vertical--your legs are calling for blood, and it will leave your
upper body (including your head), and get into your legs.
While I agree that blood flow is part of the equation, another factor
is the balance system inside the inner ear.
Think about it - you're horizontal for 30-45 minutes, but all the time
you're rotating your head back and forth on it's axis. The inner ear
gets used to this constant motion and compensates. Then all of a
sudden you stand up.
Guess what? The fluid in the inner ear is still sloshing around,
exciting the little hairs that it uses to sense motion (hence
balance.) It's the same physical phenomenon that causes us to be
dizzy after getting off one of those spinning fair rides. There's a
conflict in the brain with what the inner ear is sensing from the
fluid motion and what is actually happening.
It's a damn wonder any of us can exit the water without looking like a
bunch of drunks. <g>
