Good job!!.
My husband and I are goign through the same predicament! Although DH isn't exactly dieting like I am, he's losing extra weight right along with me (He's so very supportive!!)
His ring is so loose that I'm afraid that he's finally going to lose it for good (He has a habit of taking it off on Sunday mornings when relaxing at the computer... not sure why. Anyways, my cat loves shiny things... youg et the picture.).
Mine are quite loose and they keep slipping a bit.
What I plan to do is to get a nice thick chain and wear them around my neck and like Nelie, buy a cheap replacement band until I reach my weight goal
