I am having gastric sleeve surgery this monday. I seem to have gotten a little cold. Chest is okay just very stuffy nose. What can I take. It is hard to sleep when I can't breathe. I'm afraid to take something I shouldn't. I took an original Sudafed today because it's the only thing that works. Also a regular nasal spray which I am very cautios with. Can I use the nasal spray the morning of the surgery. I know the Sudafed is out of the question. I'm unable to speak to my surgeon right now. Thanks.
