You don’t go in and out of rehab and then you’re done. I constantly work at things.“I do hypnotherapy, which is a really big thing in my life. It works well with me because you go back into your subconscious and there are positive suggestions that are said to you. It really works for me.”She may be clean now, but her face still looks like it is feeling the effects of drugs.
