I saw a pulmonary doctor today that specializes in sleeping disorders and he scheduled a sleep study for my to test for sleep apnea. I am having it on Wednesday night. I will most likely have to have a second study if I test positive for apnea to try out different CPAP masks ... He said that sometimes they can do both in one night if you fall asleep quickly. I doubt that will happen as I have trouble falling asleep even though I take ambien.

Any advice?
