Have you used MetaSlim?

okay, so I'm thinking about using Meta Slim.
I'm wondering who used it and what their results are.
I've been using Hydroxycut for over 2 weeks and only lost 3 pounds but gained it back.
I have been really careful about what I'm eating, but the only time I excersize is when I have Gym or Dance class. whis is like every 2 or 3 days.

If I use MetaSlim, but don't excersize a lot, how much lbs do u think I'll loose?

I want to loose 15 lbs.
how long do you think that will take me with MetaSlim, but not excersizing everyday?

thanks.
