Around the same year, she went through a period of drinking, heavy drug use, and weight loss. People who saw her during the end of that year and early 2006 reported a rebound that coincided with the writing of "Back to Black". Her family believes that the mid-2006 death of her grandmother, who was a stabilising influence, set her off into addiction. Fielder-Civil then left Winehouse to revert to his previous girlfriend, leaving her in a "devastated" mood. In an interview with "The Sun" on the day of the album's release, Winehouse explained that she "shouldn't have been in a relationship with him because he was already involved with someone else a bit too close to home". During their break, she would write the bulk of the album on the state of her "relationship at the time with Blake [Fielder-Civil]" through themes of "grief, guilt, and heartache". Winehouse dated chef-musician Alex Clare briefly in 2006, and would later return to and marry Fielder-Civil in the following year.
