I cannot drink or do drugs anymore because of my liver (and mental disease) either. Spend my weekends with friends who do it though. Sometimes it is hard go resist. But it didn't do any better few tkmes I got tempted. And I keep sober. Getting more and more calm about this with time. It will not reduce the pain in my heart but it will bring a lot if pain to my body and I will most probably go nuts. Not ready for that yet.
