I've been thinking of trying this on our next cruise. I've been doing a little research and wondering if anyone on here has actually done it and what the results were?

I am wearing a bodycon dress on an upcoming cruise and am a little self conscious. We work out regularly and I am probably only about 10 lbs overweight ... just wondering if it's worth a try.

Also ... read that some people had bathroom issues after having it done for a few days. Is this typical or normal?
