As someone that cried when this happened to me here is my advice. If you have sleep apnea go on a cpap machine ASAP. My surgery is now delayed for three weeks for me to go on one. I have told people from day one I have sleep apnea. I get to my final appointment at hospital for surgery and get told I have to wait. I understand their reasoning because I do have bad sleep apnea but I wish I didn't have to wait. Plus it's really hard to get off at my job and have to tell them it was moved plus all my friends and family.
