Breastfeeding and energy drinks?

I realize that what you eat and drink goes to baby but are energy drinks possible at all while breastfeeding like maybe if u time it a certain way so its out of ur system? Idk I've been craving them so bad but refuse to drink while pregnant however I want one after I have my baby but I also want to attempt breastfeeding but whenever I have asked this question before people react like I'm wanting to snort a damn line of crack.
