With what you described at night I would suggest raising the head of your bed about 4 to 6 inches. Wood blocks work well for this. Don't just add more pillows. This can add pressure to your belly and make things worse. They do make some good wedges now if your hubby doesn't like the bed inclined, but be sure to keep you whole upper body on an incline, not just your head.
Also not eating 3 to 4 hours before laying down helps. The lump is a very common complaint with GERd and can be stubborn to get to go away.
