does anyone use them? are they any good? whats the best ones? lol as you can tell i'm looking for any info good or bad on them.

I use Medifast. The Peanut Butter Crunch is awesome, as is the Chocolate Mint. I also eat the Caramel Crunch.

do you find they help?

I love the WonderSlim caramel brownie bars, and the cinnamon crunch bars are great too. I recently received a variety box and am looking forward to trying others. The bars are handy to take to work since we only have 5 minute breaks each hour.
