Has anyone who sees this tried Hoodia? (a plant used by the San people of S. Africa and Botswana, to allay hunger pangs}. I received a bottle of Hoodia pills, which are very expensive. I have been taking two a day for about two weeks and seem to be as hungry as ever. But I have lost weight for two weeks in a row and wonder if it is due to the Hoodia, or to the fact I have doing more consistent exercise and making better food choices.
