Former NFL star Junior Seau had trouble sleeping in the last few days of his life, which contrasted what his daytime activities were like, reports USAToday.com.
The website features interviews with about 50 of Seau friends, associates and relatives which details Seau's final days. Some friends say that Seau took medicine to combat the sleeping problem.
His 11-year-old son, Hunter, told his mother and Seau's ex-wife, that Seau was up at 3am in the morning staring at the television in his bedroom, but the TV was not on. He told his son nothing was wrong.
"I know he's had a very difficult time sleeping over the years," former San Diego teammate Mark Walczak told USA Today. "I think it's gotten worse and worse. Lack of sleep creates huge anxiety." Police say Seau, who retired after the 2009 season, shot himself with a .357-caliber Magnum in the chest on May 2.
