http://www.relaxation.com, http://www.unwind-online.com (i think if not try no hyphen) these are a couple sites that help...if not try music, music is one of the sole things that calms me, if that doesnt work try doing something youlike or just simply take a ten minute break and clear your mind, do a meditation in the mornings right after you get up http://www.robinsharma.com, he knows a lot about this kind of stuff and stress relief,
thats my input anyways
