I usually put about a tablespoon of powdered B clay into a bottle of water and shake it really well and then drink it as needed. usually start with 8 big gulps and then wait five minutes to see if more is needed. Make sure you follow it with plenty of water to push it through. :)

Also note the clay is like charcoal in that it grabs toxins but also any vitamins or supplements you took on its way out, so wait three hours in either direction before taking any vitamins, supplements, or meds to make sure they get into your body.
