not being able to give it up is a pretty good indication that you are having a problem with it. Ditch the cream for a couple of weeks and see if that helps. 2 weeks in isn't lots of time, but if you continue to not see results, check the leptin reset thread. You didn't say what you were eating before, but if you were a constant-junque/sugar eater/chronic dieter you might gain a bit of weight first.
I go on a dairy fast every couple of weeks or so, just to make sure that it doesn't become a problem. It used to be very hard, and now no problem at all, especially butter.
