be sure you follow the medications for the ulcer. With weight loss surgery these can be very dangerous. I had one four months out and it took several months to heal. I still have problems keeping the mask on for the night. I wake up at midnight and it is off. Some days i don't htink it is worth it. I sleep through the night without it. I have mild sleep apnea. My pressure is only 5. They want to up it to 12 over time.  I expect to have the sleep apnea even when i lose weight since it runs in my family.

Glad your ears are feeling better too.
