Tuimoala Lolohea says he turned to alcohol at the Warriors but hasn't had to rely on it since joining the Tigers.

Wests Tigers five-eighth Tuimoala Lolohea has admitted he "drowned his sorrows" in alcohol during his final months at the Warriors as a way to deal with frustrations over a lack of opportunity.

Lolohea, who will shift to fullback next season to accommodate the arrival of Josh Reynolds at five-eighth, has shown glimpses of brilliance as he finds his feet at the Tigers.

The 22-year-old, who has shed six kilograms since linking with Ivan Cleary and the Wests Tigers mid season, has revealed the level of unhappiness during his last days at the Warriors where he was forced to play on the wing in NSW Cup.

"I got to a point where I felt that just wasn't me," Lolohea said.

"I had enough of playing on the wing. I never played on the wing growing up but they chucked me on the wing and first grade and had to stay there. I got the opportunity here to get more involved here and I feel like I'm playing some good footy.

"I was overweight. I was unhappy. I was struggling. Playing reserve grade on the wing probably didn't help. I was off it a little bit. I've lost six kilograms since coming here and each week I'm feeling better on the field. In the first month at the Tigers I was struggling and my weight had a lot to do with it."

He admitted he turned to alcohol to help him deal with the emotional rollercoaster while at the Warriors, but hasn't had to rely on it since joining the Tigers.

"I was going through some pretty tough times back home. All the alcohol ... all the little stuff it got to me," Lolohea said.

"I was drowning my sorrows in it to be honest. But I've been pretty good over here. The things I used to do back home, I don't do over here. I'm fully focused on my footy here."
