Are you using pillows to elevate your head? If so, it's not recommended. Because of the way they configure your body, they can actually create more reflux. Instead, put blocks or risers (I use 4" risers with two cut squares of 2X6, which raises it 8").
When you raise the whole bed, your body stays flat at an angle. When you elevate your head with pillows, it can actually bend at the middle and put pressure on your stomach, thus creating more reflux issues.
