I bought a Philips goLite Blue (http://www.usa.philips.com/c-m-li/light-therapy)
and so far I noticed that it is helping me get my day started. There are other models that are geared towards sleep disorders. However, supposedly the models that emit blue light work the best.

I likely suffer from delayed onset sleep disorder and my neurological issues likely the cause. I am usually low energy, dizzy and irritable in the mornings.

About a year ago I would have been afraid to use it. However, the light isn't that bad and you don't have to look directly at it.

I'd highly recommend giving light therapy a try if you have issues waking up. Remember: Supposedly blue light works best. Also avoid blue light in the evenings.
