I had a similar issue and posted recently if you want to see some of the replies...
www.healingwell.com/community/default.aspx?f=33&m=2629511I'll be completely honest, I'm up right now at 7am est because I just had a leak in the middle of the night. I am still in the "trial & error" phase and I still cannot find anything that works for more then 48 hours for me.
I wish I could say something more positive, I'm sure there is a solution that would work for me or your husband yet neither of us have found a solid fix yet. I suggest picking up some of the accessories suggested in the above thread, they are worth trying out and might be the solution you're looking for.
