It is my belief that any gain is temporary
and that when it wears off you will feel much worse.

If I was a pedantic arse
I would suggest that drinking any fluid you will only experiance a temporary gain (otherwise you would never dehydrate at all)

But that would be me being somewhat of a prick

Whilst that's true, because point 2 is genuine, avoiding caffeine is still sound thinking.
