I started taking them around late March 2006. I noticed the difference almost immediately (like in a week). I work with teenagers and i noticed that they would say that something stinks in the classroom and this reaction was only when they were near me. Once i started taking the pills their reaction stopped and so did my boyfriend's (he would tell me when the odor was present).
Please feel free to email me anytime. And i hope that this helps.
Remember to drink plenty of water and eat fruits and vegetables. I thinks this helps with the digestive system a lot.
