My Dr. suggested that the next step may be to do a sleep study. What is involved in this? I don't think I have the TIME to do this! I have two sick days left for the rest of this year, so I don't know if I should use them up for this. Is it worth it? What happens if they find out you are not getting quality sleep? I'm already taking a low dose of amitriptlyne to improve sleep quality. What if they find nothing wrong with my sleep, but I'm still sick?
