That's what I have read, but, some wine before bed seems to help relax me sufficiently that, on most nights, I quickly go to sleep. I'll sleep 4-5 hours and then awake. Sometimes, then, after a visit to the loo, I'll have trouble going back to sleep. I have wondered if it is due to the residual effects of the alcohol or did I get myself "too awake" by my visit to the bathroom?
I thought I was the only one who did that! I started doing this after one worrisome experience of having the small, loose items changing positions from where I had placed them during the night because of the train's motion. In the cramped conditions of a Roomette with the door closed and the bed in place, it's difficult enough to stand/move, etc., let alone trying to find small items that are where?
Yes. I am more comfortable dressed like that since that is the way I dress at home. Helps to promote sleep, I think. Used to wear a robe when going to the restroom during the night. Stopped doing that. I am properly attired, the robe takes up space in my carry-on, and, if someone sees me and doesn't like it,: then, stop looking.
