White tounge= Bad breath?? HELP!!!!

I have been having issues with breath odor and white tounge. I brush, I floss, I tounge scrape, but i think the odor is still there. I am somewhat self conscious and I am really at a loss. I have been told that it could be my diet, my colon, my teeth...I am at my wits end and i need a solution. Has anyone experienced this? I can say that I don't drink as much water as I should, but I'm working on that...now drinking a half gallon per day. Could this be the problem?

HHHHHEEEEEEEELLLLLLLPPPPPPP!!!!! PLEASE!!!!
