According to the NME Amy Winehouse's "exhaustion" appears to have been drug-releated, hence her recent retreat from rehab. She left the center with her husband via helicopter, which seems like a pretty awesome way to skip rehab. Her father-in-law Giles Fielder-Civil was quoting as saying: "Amy has had five days away from drugs and her self-esteem and confidence is slowly coming back. I hope she and (husband) Blake can take control of their lives."
