Just days after the tragic death of singer Amy Winehouse, the family of the 27-year-old Grammy winner now claim that she may have died from alcohol withdrawal.

According to family sources, Winehouse ignored her doctors request to cut back on drinking gradually, and that her 4’11″ figure couldn’t handle such a dramatic change.

“Abstinence gave her body such a fright they thought it was eventually the cause of her death,” a source told The Sun (via PopCrush).

As of this week, the official cause of death has yet to be determined.

Winehouse died last Saturday afternoon inside her London home.
