TTC with a snoring spouse?

My husband has recently gained some weight and now he's snoring really loudly. He shakes the bed when he snores. he even wakes himself up from the sound and vibration. I bought a noise maker and slept with earbuds playing white noise it didn't help much. We've been sleeping in separate rooms and I can still hear him through the wall. He's gotten a sleep study and they determined he doesn't have sleep apnea. So no help for us medically. Needless to say this has been a little crippling in the baby making department. We are both usually tired from not sleeping and not in the "mood". Intimacy between us is suffering. Does anybody have suggestions?
