Hey there Buds,

Does anyone have any info on these so called energy drinks? I had one yesterday (instead of taking my usual serving of NO explode) at work I think it was called Monster assault it was fckuing nuts I was bouncing off the walls when we went for our daily workout. Anywho, I was curious to know if this could affect my supplementation (I'm currently taking nitrix and viraloid). Does the caffeine, taurine, ect. affect the bodies oxygen levels? If so how and why? Another thing is I was more tired than usual after my workout why was this? All feedback is appreciated, Thanks TEXFIRE
