The results from your sleep study will help your doctor choose the appropriate treatment for your particular sleep problem. Patients are entitled to obtain a copy of their test results. These are not hard to interpret and are very informative. Going for the sleep study is a positive step towards a better night's sleep and a more alert day. The staff is well aware that this is a problem and do not expect that you will be able to sleep just the same way as at home.
Great effort is made to make the environment as friendly as possible.
Also, remember, people often sleep two or three hours without knowing it. A great deal can be learned from just a few hours sleep. Do not worry if you do not sleep at all. You and your doctor will discuss the next steps. Generally, a sleep lab will not give you medication to put you to sleep.
