Everyone here is talking about alcoholism .. although he is probably an alcoholic his drinking is something you know about and I don't think he would be stupid enough to lie about it. (but then again I have a brother-in-Law who is an alcoholic and lies about everything - but he has always been that way - sober or straight).

I have an ex-wife that was doing the exact same thing and it took me nearly a years to figure out she was doing crack cocaine. Crack/and other drug users have a very distorted version of reality .. they think/or don't care if people can see the obvious. They will lie about everything to everyone (including themselves).
They truly believe what they are saying.

Is the lying something that started in the past couple years or has he always been this way?

No matter what the addiction, your husband needs help. If he refuses then you need to use "Tough Love" ... kick him out.
If this does not change him, or he does not want to get help .. you are better off.

This may sound cruel but I have been through this and you and your daughter will be much better off in the long run.
