creatine and caffine question? Help

[toughenough]

I'm on CEE and I can't find anything that says if the effects of caffine will counter act the results that I've been getting from the CEE. I've heard people say that you should avoid caffine while on CEE, but I want to know why. I'm a huge coffee addict and now that fall is here I'm drinking coffee too. Should I stop CEE or am I ok?
