Brooke Mueller in rehab for 19th time after abusing Adderall

Brooke Mueller has gone to rehab for the 19th time after privately admitting that she has been abusing Adderall. Last week, Mueller was rushed to the hospital for a suspected overdose after she was found unresponsive in her home. Mueller insisted she was simply sleeping; she'd been awake for an extremely long time making jewelery.

Turns out, she'd taken far above the recommended dose of Adderall in order to stay awake that long. Though Mueller does have a prescription for the drug, she admitted to friends that she'd taken many pills, which resulted in a crash.

Mueller has checked herself in to a facility that she's stayed in before. "Brooke was uncomfortable with the way Adderall was making her behave," her attorney, Yale Galanter, tells TMZ. "Brooke continues her lifelong battle with drug addiction by taking these steps herself to prevent a further drug relapse."

Her two children with Charlie Sheen, twins Bob and Max, are with a nanny.
