The outspoken actor's show is set to stretch into Canada and continue through May 3.
Sheen announced his first two live performances last week on his Twitter account. Those shows, which are slated for Detroit and Chicago, sold out very quickly.
Earlier this week, Sheen added an additional five dates. He tacked on a dozen more late Thursday, including stops in Toronto, Atlanta, Houston, Dallas, Denver, San Francisco, Seattle and Vancouver, British Columbia.
Sheen has not revealed the content of the show, other than to call it "the REAL story."
Tickets for the latest dates go on sale Saturday.
The 45-year-old actor was fired from "Two and a Half Men" in early March.
He sued the show's producers Thursday for $100 million for breach of contract. Hours later, he reached a custody agreement with his estranged wife over their twin sons.
