Hi, I've been reading these forums fairly consistently for the past 8 months or so, but never really bothered making an account, because I never really had anything to ask/answer.

Unfortunately, I've only had about 2 brief instances of lucidity during that time

I've tried several techniques, the most frequent being WILD, because it is the most convenient for me, and I've gotten the closest to a full lucid dream this way.
My main problem at the moment is attaining SP so I can successfully continue with WILD.

I was always able to begin to induce SP since I began experimenting with lucid dreaming, but have never successfully followed through.
I'm able to reach the vibrations, numbness all over, ringing/pressure in head, when suddenly it stops.
My heart rate randomly increases, my chest tightens, and it feels like I'm suffocating. In other random/odd cases I get an erection [awkward ] or some other distraction arises. I always am fully aware, and keep telling myself to stay calm, and keep my steady breathing, but nothing seems to work. The vibrations fade, and the numbness stays until I move. I have to get up, roll over and start over in order to try to induce SP once more.

I'm SO close. I know I can do it, but my body flips out at go time.

All and any advice is welcome, so by all means, lay it on me.

Thanks bunches =]
