i just bought a fully body cleanse from GNC, going to try it very soon. does liver, kidneys, colon etc...cost is cheap. takes 7 days and i've heard it works well...there are plenty of other ones that are more potent, but stick to something light the first time..apparently you should do one every year...no harm in giving it a go.. the reason i got it cause i've been bloating alot and having trouble with digestion and this helps.. people report that they feel great after, so i'm keen to see how it goes
