Variations in the body weight of rats trained to a system of voluntary consumption of ethanol. The solution was made accessible to the animals from 11:00 to 13:00, every day for 3 weeks. The body weights of both GH (□) and SI (▪) animals have been measured 3 days a week, for 3 weeks after removal of ethanol solution (at 13:00 h). Data are expressed as Mean ± SEM of 20 rats per group.
