Tried it tonight.

I put the phones on and turned to my side like i usually do when sleeping. I waited for about 20 minutes but the fact that i was hearing a beep and had a phone on my ear couldn't let me sleep. So, i just took it out and went to sleep as usually.

What happened was that, later on that night, without even trying, i had 3 spontaneous SP episodes which was odd. I haven't adapted to the transition yet so i didn't have an efficient WILD but i don't know if these episodes were related to me using the mp3 before.

Anyway, i might try this again some other time as i never had so many SP episodes in one night before and my late attempts had been frustated.
