Do u have one? Mine is sugar... it just might be the death of me....ice cream is just too good. I've tried to give it up and I could only do it for nine days. I noticed a difference in my eyesight, my skin....but my cravings got the best of me...I gave up my stashes of candy...gave up soda (way too much sugar) but I cannot give up ice cream...I just can't. Giving up sugar is harder than u may think.
