night light and tamoxifen resistance....melatonin

Interesting! Is anyone taking melatonin as a supplement? Anyone modify their bedroom/sleep schedule effectively? I am getting rid of the electronic clock and cable box (we never watch TV in the bedroom anyway) but wondered if we should also get darker shades to prevent outside light from coming in (neighbors / street lamps). Thoughts? I do like our thin shades because I like waking up as the sun comes up, and gradual light in the morning seems to make that easier.
