So I'm going to attend a McGuire program course on Wednesday...... The McGuire program is an intense few day course that works on breathing techniques and the like. It's a big price, but I get to experience a day and a half of it before I pay. I'm going to put 100% into it, and I'm pretty confident it'll work. I'm just wondering if anyone has had any experience with McGuire or if anyone here has done it?
