I have Sleep Apnea and need a CPAP to sleep. I left my Nasal pillow in the bathroom at the hotel room in San Antonio, Texas. I had to order another so I can have a full nights sleep. Every place I called would not sell me the part I needed without a prescription from my doctor. My doctor is in San Leandro, California and I was in Corpus Christi, Texas. The company that I usually get my medical supplies from is Apria and they could ship me the nasal pillow in two weeks. So I then looked at Amazon and they have two day shipping. I knew we would be in South Padre Island in two days so I had them ship it to the place where we would be staying.
