Since I have SAD I use a light box daily...it provides full spectrum light which is supposed to take the edge off depression (it's very cloudy in winter where I live). I'm also on a low dose AD & Abilify (which is both an AP & is supposed to increase the effectiveness of ADs). With all this mix, it's hard to telll what's what, but the light box certainly doesn't hurt. It's never made me hypomanic, but if I use it late at night I find it hard to sleep.

Not all light boxes are that expensive. Amazon has a wide selection of light boxes in various price ranges:

Good luck working your problems out. I don't blame you for wanting to get of Seroquel...
