Wow! I was just about to suggest concentrating on breathing too, and there it is. Great minds and all that.
saoi, I wouldn't worry too much about sitting quietly, because if you are doing, then you're resisting what is, and creating tension. If your mind wants to wander, let it wander! Who says that the wandering isn't part of the process of change as it relates to you?
I do like the Paraliminals, and have had excellent results with some of them. If you are familiar with my posts on here, you'll see I don't hold back when I think something isn't up to scratch, so you can count on a recommendation from me as being honest.
You DO need to have a clear goal in mind when using the Paraliminals though, so please do bear that in mind as a fuzzy goal will affect the outcome.
