Are they the wedges? I had acid reflux caused by a hole punched through my stomach from taking Diclofenac for too long. I looked at the wedges and thought they were rather expensive, so grabbed a whole load of old towels, folded them and raised just my side of the bed with them, so that instead of a wedge my whole body was on a slope. Then I used three pillows. I also found that I couldn't sleep on my right side at all.
It has wonderful side benefits too - it meant that DBH could no longer try to hog the whole bed, as he just rolled back gently to his own side!
