I asked about Alli in conjunction with WW a while back and pretty much everyone said if you're following WW properly, there should be minimal fat to flush our your body to begin with and they're not worth it.
Needless to say I didn't buy any. xD
You're damned if you do and damned if you don't with them. If you don't eat much fat they're a waste of time, if you do....well the results are...*ahem* not pretty. :jelous:
