Nikki Sixx, the bassist and co-founder of the rock band Mötley Crüe, had been through multiple stints in rehab and had been open about his struggles with substance abuse. However, specific details about his life after leaving rehab at any particular time might not be readily available or publicly disclosed.
I recommend checking more recent sources, such as news articles, interviews, or official statements, to get the latest updates on Nikki Sixx's life and experiences post-rehab. However, remember that personal matters might still be kept private, and any information shared should be done with respect and sensitivity to the individual's boundaries.
