Craving not allowed!!

Oh my goodness, I am craving a chocolate chip mcfrappe from McDonald's! I'm 13 weeks and I have stopped drinking caffeine. Every once in a while I have a sip of my husbands soda but nothing serious. Anyone else having cravings for stuff that your not really allowed to drink/eat during pregnancy? I know I have read a cup of coffee won't hurt the baby but I'm the paranoid type. Any advice on things that I could eat or drink that might help stop this craving?
