Life in Rehab

Since checking into Wonderland Center last week, Lindsay Lohan has been keeping a low profile. "She's been sending text messages from rehab saying she's the happiest she has ever been," a pal tells PEOPLE. "She seems under control now." Lohan, who had planned to attend the Sundance film festival, has instead been taking hikes on the center's three acres and attending treatment meetings.

The facility has all the amenities of a spa, including yoga instructors and beauty consultants. Dr. Howard C. Samuels, the center's executive director said, "We treat the individual's emotional, spiritual and physical ailments."
