Struggling with food cravings

I am overwhelmed.  I am struggling with controlling my cravings.  Right now, I am not craving anything.  I wonder what can control cravings.   I crave peanuts one day and almonds another day.  I may have a sweet tooth, so I crave something sweet.  I am just struggling while I am on Weight Watchers.  Maybe this is just a part of the program.  I have no idea what I am doing, but I will stick to it.  Life like weight loss, is a journey.  I must remember that.  I was craving for peanut butter but I have to remind myself that I am sharing a house with another person, who also likes peanut butter.  I too must remember that.
