Let me clarify my post. I did not mean to imply that acupuncture doesn't work or that it's a load of bull. It works. And I know many people it has helped. Just not me. I think there are things that can be addressed with acupuncture and things that cannot like heavy metal toxicity but it doesn't hurt to try. It certainly did not make me any worse. And after each treatment, you DEFINITELY feel it. If you go too strong, you'll feel lightheaded and scientifically, small tiny hair sized needles in certain points shouldn't have any effect on you.
