mountaingoat, I like the advise, but suppose, you've been showering as a 'wake-up' forever? Won't the PM shower also, wake you up?
The daylight thing is a problem for me, too...I always shut off the alarm, and stand at the window for a minute. Now we're coming on winter, it's DARK when I look out!
I guess nothing is for sure, but I DO have my Xanex!
