in good shape?

I always felt that I am on the heavy side. But at the office, I feel like im the smallest, funny huh?! Since im prepaparing for my vacation in manila, i really wanted to look good and feel good about myself. You think it is safe for me to drink some diet pills ? i Have seen some products online, and they guarantee safety and effectivity of the product, so im thinking of giving it a try. I hope to shed off a few extra pounds so I will look better with the new clothes I have.
