Will it be hard to fall asleep?

For some people it may take a bit longer, but don't worry - just let nature take its course. People usually fall asleep pretty quickly. 

What if I need to use the bathroom during the night?

Just let the technician know you need to get out of bed for any reason. Unplugging and reconnecting the sensors is fairly quick and easy. 

What if I change positions a lot when I sleep?

You will be able to roll over and move around in bed during the study. In most cases, it does not disrupt the sensors.

Can family members stay overnight? 

Usually not, unless there is a medical reason and arrangements have been made ahead of time with the sleep lab. The exception is for patients under 18, in which case a parent or guardian must stay with their child overnight.
