I use vista on my laptop. ....not that it really matters.. yeah. Back on point, I suppose the cube doesn't really remind me where I am and all that, it just, I dunno, keeps me in my body. You know when you watch a film, you get so engrossed you don't really think or notice the chair under you or where you arms are, etc. The cube helps me stay focused on my body, while I do things that normally make people forget. I suppose it helps while on the computer, but everywhere else, I guess it's going to take practice.
Also, how long did it take you guys after starting this method to have an LD?
