Lindsay Lohan -- Cooperative, Clearheaded

Lindsay Lohan is actually handling jail well, sources at Lynwood tell TMZ.

We're told she's "polite, compliant and responsive."  She's not crying and is handling it well.

And there's good news for the newly-minted jailbird.  A Sheriff's official tells us she will probably be released around August 1, after serving only 13 or 14 days.   A lot better -- for her -- than 23 days behind bars and, even worse, without cigarettes.
