At least before shows. Amy, who is famous for getting really drunk before shows and skipping out has vowed to quit drinking before she has to sing. A source tells The Sun that Amy's dad was worried, especially after being caught with weed last week, so she's promised him that she won't start drinking until after the show has ended.

“This tour started pretty much as the last one ended.Berlin was a difficult time for everyone and we thought it was going to turn into another tour full of drunken and missed shows.

“But she’s now said that she will not drink before her gigs for the rest of the tour.

“She stuck to it in Amsterdam, amazingly, and gave her best show of the tour yet. Everyone just hopes she keeps it up.”

Yeah, how long until she cracks on that promise. I love me some Winehouse but she's as fucked up as fucked up gets. But she's got talent so hopefully she gets her shit together.
