I did to an extent but I don't know if I could pin it entirely on leaving the borg. I used to binge drink as a student, but then few students don't. I also smoked weed recreationally of an evening for a few years. However I have an illness (Fibromyalgia caused by insufficient levels of Serotonin) that improves with use of the drug and was advised (off record) by a specialist consultant that it would help! It did.
I'm now on anti-depressants partly for the illness, and mainly due to PTSD which I now see is definitely linked to feelings of guilt, shame, loneliness etc as a result of coming away from the borg's control and straight into an abusive, controlling relationship with my ex-husband.
