Well, it really does depend, just like physical training, everybody is different. Most people notice a change within themselves after just a couple of sessions, some people don't notice it at all until something happens that would usually cause stress or anxiety, and they don't react like they used to. Between 8 to 10 sessions should have you on the right track, and seeing things totally differently in your life. Another 10 would cement this change. But, if you are anything like us, you'll love it. You'll love having that hour of 'me time' to relax and re-balance yourself, and you may want to continue with training every fortnight or so.
