Last September former England boss Fabio Capello warned Carroll that he needed to "drink less".
Andy Carroll: "My past is my past. I changed my lifestyle when I came to Liverpool and settled down. I love it here.
"People will say to me 'Oh, you were in the boozer last week' but it is just rumours going round.
"Now I just laugh it off. To be honest, I don't go out at all.
"All I do now is sit in the house with my girlfriend, chill out and watch movies.
"As for the team, I am confident in myself that, if I am playing games, I will score goals and put myself about.
"I cannot really do that if I am on the bench and coming on in the last 10 minutes of games.
"What I want is to start games and put myself about like I know I can.
"When I haven't been playing, you get low on confidence."
