Diet pills?

I know that diet pills are bad for you but simply if you use them for a long time. Does anyone on here have any that they enjoy used and had great results? I single want to lose like 20 pounds. Can anyone lend a hand me out on what worked for them? I've used them and it did nothing for me except receive my heart race so speedily i thought i was going to own a heart attack.
no believe me it hardly works
