I attempted to night wean as well at about 14 months using the Dr. Jay Gordon method. I didn't carry it out 100% but we did drastically cut down. For the reasons you stated as well we are trying to get Max in his own bed. He is a really restless sleeper and wakes me up constantly. I have gotten to the point of putting him to sleep in his crib, and co-sleeping the 2nd half of the night as we have a hard time getting him back down when he wakes up at night.
I am a firm believer in co-sleeping if all parties enjoy it and for us I really don't enjoy sleeping with my child running and playing soccer in his sleep! Maybe if you just weaned from cosleeping but continued to nurse at night it would cut down on night feedings and you and dh would sleep better together when he returns.
