When I started having sleep issues, I talked with my doctor and I think that I actually convinced him to prescribe sleeping pills for me. Luckily, instead of becoming addicted and dependant on them for sleep, I hated how they made me feel. It was then that through my counsellor I was intriduced to guided imagery on CD's.
I stumbled accross a CD at Barnes & Nobles that is produced by a company called "Meditainment". They have a website that I've ordered several more CD's from. They are from the UK and have those awesome accents, and the music and sound effects that they use are phenomenal!
I guess the best thing I can say about guided imagery CD's is that I seldom hear how they end!
