The past few nights when I WBTB and WILD, I've been using the count-your-breaths method. I always seem to get to around 325-400 breaths, and then my mind starts to wander. I usually end up getting so bored (because I don't feel very much SP action going on, I actually don't reach SP at this point, I'm just numb-ish) that I roll over and fall asleep. Do you think I need to work on my focus, or change to a different technique?

Some people say that I need to "passively" count (or count in the back of your head without really thinking about it, you know, an anchor)... but I don't really know how/can't do it well.
