Samantha Who? (2007)

Samantha Newly has been a bad, bad girl. But thanks to an 8-day coma, she can't remember a thing. Fortunately her best friend Andrea is by her side with a cocktail and the 4-1-1 on every dirty deed. But the more Sam pieces together her past, the less she likes her old self. Maybe this is a chance to start over and do it all again.
