I just drank half of one of those "Extreme Energy 6 hour shot" things, cos i thought it would make me wanna play poker. (i drank half because it said to prolong the effect to the whole six hours you should drink half, half in 3 hours).

Then i started into a session of 2/4 and when the drug took effect i began having partial blindness.

Let me explain. I was having blind spots, blur spots actually, and was having trouble seeing whatever i would focus at. At first i thought it was just that my eyes were dilating and that the screen was too bright. So as an experiment I closed one eye. Then i could see fine.

So basically i think its fucking with my ability to focus binocularly. To be specific, there would always be a blind spot to the right of wherever i focus. This was causing me to misclick a lot because whenever it was my turn to act preflop, I wouldn't see that someone had already opened to my right and would 3bet them accidentally.

Has anyone ever had this problem with an energy product. There are no listed side effects of this nature and i can't find anything on the internet to shed some light.
