Tila Tequila has a bad case of the sniffles -- and it has her headed for Celebrity Rehab 4. After much speculation, sources are coming clean with the dirty details on Tila's substance abuse issues. As it turns out, the bisexual babe's drug of choice isn't crack or meth but an addiction to snorting the sleeping pill Ambien. The former MTV reality star is set to appear on Dr. Drew's Celebrity Rehab 4 where she will battle her dependency on the sleeping pill. An insider says that Tila revolved her days around getting high. The source tells Radaronline.com that the Shot of Love celebrity would indulge in a real breakfast of champions, "She would base her entire day around it. She would wake up, snort ambien, google herself, do more, Twitter all day and then sleep." Somewhere in between, the troubled D-lister would find the time to stage whacked-out photo ops, some of which included her in the produce section decked out in lingerie. Of course, Tila has plenty of incentive to clean up her act. Supposedly, VH-1 has offered her a reality show on her sober life if she completes Celebrity Rehab 4. Tila took to her Web site to talk about her uphill fight, "I KNOW I am an EXTREMELY smart girl, and to run all these empires when I am not even 30 yet, is quite an accomplishment, however I finally admitted to myself that I cannot rely on taking prescription pills everyday for the rest of my life! I MUST not be another "LINDSAY LOHAN" where I just flush everything I worked so hard for down the toilet for nothing..." Um, in order to lose everything TIla, you had to have had something.
