Hi you can try a snoring mouth guard as an alternative to CPAP. This is what my husband and I are both using for our sleep apnea (throat airway obstruction) http://slumberguard.com.au/ :)
Hi, do you use a mask?. The pressure from the mask can cause swelling around the eyes. You could start by trying them for very short periods and then increase the timing as you get more comfortable. Alternatively, you could try BiPAP, which is a bi level pressure device, which regulates according to inspiration and expiration, and hence is more comfortable. Also check with your doctor to rule out other causes for the swelling like allergies or kidney disorders. Regards.
