You know when I decide to diet I never had trouble letting go of caffeine. I'm not sure why. I got headaches the first couple of days probably due to giving up caffeine but I was never like "OMG I NEED A COKE!!!!" X_X
I think keeping yourself busy by drinking loads of water helps. Try not to think about it.
Congrats on your 2 weeks KayMaxim!!

Keep it up!!
