Later that year, he released En las Buenas... y en las Malas with the lead single "Amnesia" reaching number-one on the Hot Latin Songs chart. Two years later, he released 40 y 20 in which the title track speaks about men who fall in love with women that are much younger than them and the reaction of the society to those situations. By the early 1990s, José's vocals began to deteriorate. It worsened over time and became evident in his live performances. His excessive drinking and unceasing activity of his career caused his voice to falter. In August 1993, to commemorate the 30th anniversary of José's career, BMG hosted a tribute in the city of Puerto Vallarta. It was called 30 Años de ser el Príncipe (30 years of being the Prince). The tribute included some of the most prestigious artists of Spanish music such as Rocío Dúrcal, Camilo Sesto, Armando Manzanero, Marco Antonio Muñiz and Raúl di Blasio. The tribute coincided with his recent divorce, a serious relapse into alcoholism and a significant loss of vocal abilities. He appeared to be in poor physical shape, too thin and lacking energy. Camilo Sesto even took a break in the middle of the presentation to speak words of encouragement. The album was not released until 1994. At that time, José suffered the worst stage of alcoholism of his life. During 1993, he retired from the stage and went into rehab. Upon completion of his rehabilitation, he started seasons in places like the famous "Teatro Blanquita" of Mexico City, and the Gibson Amphitheatre in Los Angeles, among others. In 1994, José José reunited with Manuel Alejandro and released the album Grandeza Mexicana. The title track peaked at number 12 on the Hot Latin Tracks. He recorded a duet with his son José Joél in the song "La Fuerza de la Sangre". In 1995, he played the lead role in the movie Perdóname Todo, a drama about an alcoholic has-been and how he tries to survive against himself and the music business. That same year, his album "Mujeriego" was released. It sold more than 180,000 copies in its first two weeks and reached number 12 on the Billboard Latin charts. The song "Llora Corazón" peaked at number 6 on the Hot Latin Songs and was nominated for Pop Song of the Year in the Lo Nuestro Awards. In 1996, he performed a duet
