It definitely is! I know my mom uses one of those machines at night and had to go through observed sleep studies. I wonder if they have a home monitor for diagnosis. I’m trying to imagine doing one in a hospital setting and them getting frustrated ( and me going broke) after I still haven’t fallen asleep after 2 days. I will definitely ask about it. I’m trying a therapist when I get back to the states and focusing on CBT for sleep hygiene and whatnot. I’m not sure how that’s going to work, but I have a sleep-log to start keeping track. Thanks!
