I chew gum. This also helps when I have to wait half an hour after eating before I can drink anything. Sometimes my cravings aren't for anything in particular, I just miss having something in my mouth and chewing. It's particularly bad after a fill when I have 2 days of liquids before advancing back to a normal diet.
If I'm going to have cravings, more often than not they will occur for me between the hours of 3 and 7. This has always been a problem time for me.

I wish I owned stock in Orbitz.
Find out what triggers your cravings. Sounds to me like it's boredom for you at the moment. I can relate to that, being a stay-at-home-mom. Get yourself busy. Clean out a drawer (the junk drawer always needs attention), compose an e-mail, go for a walk, read a book, do a crossword, rearrange your wardrobe, polish some shoes, do some ironing.... there's always a chore that needs attention.
