I say go for it... but be informed about it... you need to eat right and exercise, but the Trimspa will help speed this along... and since it is Ephedra free, it should not pose a major health risk like Ephedra can.
I know I am going against everyone else here... but when I was nearly 40 lbs. heavier, I started to eat better, go to the gym, run a bit... I tried Xenadrine (then it still had Ephedra).. I ended up going from about 195 down to 159, at my lowest point... but the key was, I followed the instructions on the bottle, I ate healthy, and exercised... after the bottle was gone... about 6 weeks or so... I did gain back about 5-8 lbs... but it wasn;t too bad...
Good luck.. let us know what you decided to do
