Anyone else have a problem focusing on days they workout?

[Gobias Ind.]

For some reason post-workout:
-I steam like it's my job
-I have an overall feeling like my head just isn't clear.
-I'm not seeing all the angles. Simple [censored] that is purely mechanics, that I'm screwing up.
-I call down a LOT more when I'm easily beat


Can anyone explain why this might be happening?

Note: This isn't the first or second time that this happens to me. It is almost as if its so bad that I need to choose between getting/staying in shape vs. poker
