Heather Locklear's Family Wants Her In Rehab... Again

Heather Locklear's family wants her to check in to a medical rehab facility as soon as she's released from the hospital ... but Heather is resisting ... TMZ has learned.

Sources directly connected with Heather's family tell TMZ ... yesterday was not an isolated incident. Heather has been struggling with prescription drugs for a long time. In fact, sources say Heather checked in to an L.A. area rehab facility last October and stayed 2 weeks.

We're told Heather's family wants her to go to a medical facility this time around -- not a rehab center.

But so far ... Heather is resisting.

As we first reported, Heather's sister called 911 Thursday just after 2 PM PT and said she had taken a dangerous mixture of prescription drugs and alcohol. She was hospitalized in serious condition.

Heather is currently in the ICU of the hospital in stable condition -- and earlier today, she got a visit from her sister.
