that's awesome! losing a ring size is a huge accomplishment.
my guess would be that they are accurate.. and if you're right handed, that would explain why they fit better on your left hand. whatever hand you write with is always a little more
buff than the other one.
i know one of my NSVs is going to be getting a ring i'm wearing OFF! about three years ago, i weighed 135 pounds and always wore a ring on my right middle finger. i never took it off, but i could have if i'd really wanted to. well.. i gained 100 pounds and now it's stuck! i'd have to cut it off to remove it. at my highest, it left a little indention in my skin and kinda looked like it was strangling my finger. now it moves around a little more, but i'm still a long way from getting it to come off. when i finally do.. that will be the day!
you'll probably have to keep a check on your wedding ring from now on though. i'm sure it's just a matter of time until it goes flying off your finger!
you're doing so welll! keep up the good work
