liver disease and enlarged prostate

My husband is also suffering from an enlarged prostate, that due to his liver disease he cannot take any medication for. He gets up several times a night to urinate. This makes it hard for him to get the rest that he needs...and it disturbs my sleep too. The good news is that he can easily fall back asleep. Anyway, just wondering if there is anything out there that can help with this. Grateful for all suggestions. Foods...juices...whatever.
Thanks!
