Re: sleeping hours

I bought inexpensive black out block out, canvas vinyl type white curtains at walmart. they block out all the light and any glare. they were invented by a pilot who worked the night shift and he needed to sleep in the days, so he invented these black out curtains so he could sleep. they sell them at linens and things, target I think, and other stores too. An eye mask is a cheaper way to block out light and glare.
Also, ear plugs are good too.
