I totally agree with DrFrank, I have been trying this lately instead of reading, using computer, or watching t.v. I lay and focus on my breathing as well as listen to guided imagery audios. You can even find relaxation videos on youtube or maybe cds from your local library. I also drink milk before turning the lights off, about 1/2 cup of milk.
I can't say it will work all the time, but so far I am seeing improvements and the mediation has also improved my self esteem. Good luck!
