I have lost close to 60 lbs in the last two months, which is great! But now that my tummy is shrinking, it also appears to be falling (gravity sucks, doesn't it?) It seems now my tummy is pressing on the front of my hip and often almost makes me fall, it feels like a rubber band slipping...anyone else experience anything like this?

In all honesty no. Have you ever considered yoga? It has really helped me regain balance in the post weight loss universe.
