I caved into cravings last night-am I screwed?

So I am now on Day 6, but last night I caved and had a slice of cantaloupe. It was late and I was soooo hungry. Have I ruined this for myself? It was really good as I ate it, but afterwards I felt like crap that I had not stuck to the cleanse. I am just wondering if I should still continue. I am just not sure what it did to the effects of the cleanse. Will I have to start over? Also, how does everyone curb those late night hunger pangs or cravings? I even had them before the cleanse and could never hold back giving in.(one of my biggest reasons of beginning this cleanse-gain willpower.)
