Sometimes this is necessary to fully diagnose your sleep disorder. If you need to stay for daytime naps (MSLT) we will wake you around 6 am and feed you breakfast and lunch (we have a menu and you can pick what you’d like). You will be taking naps at 8 am, 10 am, 12 pm, and 2 pm with an additional nap at 4 pm if necessary. You may not have any caffeine during the day.
