Drinking & Breastfeeding!???? Help

I'm a new mom, but I went out to drink tonight to celebrate my birthday. My baby just turned one month today. 
I drank two Jagger bomb, how long do I have to wait till I am able to breastfeed???? 
If I pump I'm I able to dump it then wait two hours later to breastfeed him, or do I have to dump again two hours later??
