I learned the hard way that taking too much at once gives me a headache. I take plenty of water with it - at least 1.5 glasses when consuming about 1 tbsp (I don't measure; I drink direct from the bottle, since all my spoons are metal and metal is said to reduce effectiveness).
I don't have constipation. Sometimes I find it a little harder to use the bathroom, but the majority of the time, it comes out very smoothly. (Though I do, at times, have slight fatigue or a slight spaciness that is removed by using the bathroom, so that may be related to toxins being removed from the body) I feel like I'm on the home stretch to curing my symptoms overall, and I'm real excited about the progress I've made, currently using a mixture of Bentonite
clay, Heavy Metal Cleanse by Renew Life, aloe vera drink, l-glutamine, and the anti-candida diet. I also have so much energy overall that I go for bi-daily bike rides for nearly an hour each time. Things are looking up.
Now, a coworker actually bought me a plastic container that can be used for foot baths (I was giving her health advice, and I'd helped her in the past with other stuff, plus I have an upcoming birthday :P).
Anyway, using Yerba Prima, what specific instructions do you have for taking foot baths? Use a cup (i.e. like half the container) into a certain amount of warm/hot water and soak my feet for 30 minutes? Do you feel detox symptoms after or during a foot bath? I didn't.
