I'm only halfway to my modest goal, and my rings are becoming an issue. I've worn the same one on my right hand for nearly nine years, and my engagement/wedding ring for three-ish. Both are wiggly as all get-out right now -- just enough to be annoying throughout the day, but not quite in fall-off territory yet. I'm only 10 lbs lighter than when I got married, so I'm really surprised that it's an issue already.
I have terribly small hands/wrists to begin with (I think my rings are 5.5? shoot, I should know!), and I'm a little wary over how much more they'll shrink. Re-sizing them is in the future, but I'm nervous about doing it now and then having my fingers shrink even more. I suspect my wedding ring may have to be re-cast, so I'd hate to have to do it twice. But at the slow rate I'm losing - and expecting this problem to only worsen - I'm not sure what to do between now and then. Closer to goal, I may have to put them on a chain or just stop wearing them temporarily... blah.
Anyone care to share their experiences with their rings? I know about the existence of 'sizers' you can clip on the band, but have never actually seen them or know if they work very well.

GL. I hope you find a solution and it's easier than mine!
