SusanEllen, Yes, bring your own pillow and blankets. I should have done that. Make sure you adjust the room temperature to what you're used to. I would also try to arrange your sleep time with the sleep tech so that it matches your normal sleep time as closely as possible. I'm a night owl, so they let me go to sleep later, about 11 pm, which helped. I also brought a book and some music on CD to relax to, which helped me relax until they wired me up for the study. I was actually able to sleep, but not as well, of course, as in my usual sleep environment. I was allowed to take a sleep drug (zolpidem 5 mg) which helped me get to sleep.

It looks like a CPAP may be in my future because while my sleep apnea is mild I have symptoms excessive daytime sleepiness and fatigue.
