I don't have sleep Apnea what happens now?

I am a little neverous about what happens now. I did my sleep study and I couldn't sleep. I don't have to go back for a second night and they did not put the mask on. The tech said she didn't realize the importance of my test (lapband surgery****il this morning when the test was over. I don't think I have sleep apnea. I was already approval. I have a 36.7 BMI, Depression, joint problems, asthma, and the on set of diabetes. Will not having sleep apnea change my approval status? Surgery date July 17, 2008
