Capri Anderson: Charlie Choked Me, I'm Suing

Capri Anderson made alarming allegations about that infamous night she spent with Charlie Sheen -- including claims of alleged drug use and abuse ... and she says she'll file a lawsuit today.

Anderson, who sat down with "Good Morning America," described Sheen snorting a "white powdery substance" and recounted the moment when she felt things took a turn for the worse, saying, "When I became really uncomfortable is when he put his hands around my neck."

Sources connected with Charlie say he did absolutely nothing violent. 

  Anderson -- who was there with her lawyer, Keith Davidson -- said she plans on filing a lawsuit in Los Angeles Superior Court.

UPDATE 9:10 AM PT -- We shot Capri and her lawyer heading into a law office, where the lawyer stated Capri plans on suing for battery and false imprisonment.
