Good question!

I'm curious about that too. I put on the castor oil pack and then wear a Depends over it. The elastic on the Depends holds the flannel tight around my abdomen so I've been leaving off the heating pad and just wearing the pack all night.

I've been doing it the last three nights and haven't seen any effects, so maybe it doesn't work without the extra heat? Then again I have lost weight so maybe it is the castor oil? I dunno... Tweet
