I am having a problem with cravings and being vegan!?

I KNOW that animals are tortured and murdered for the meat eaters' pleasure, and I KNOW that there are hundreds if not thousands of chemicals in meat and dairy, BUT I am getting cravings for meat and dairy again. I have only been vegan for 2 weeks. Am I just going to have to watch a PETA video everytime I start to crave a McDonald's snack wrap? I know it sounds like I'm being a smart alec, but I'm not. I have really been struggling the last couple of days and I was wondering if any of you had had this problem? Thank you soo much for your help! *huuugs*
