Anecdotally during a period of 3 or 4 months when I had gone to numerous Ayahuasca ceremonies here in Canada, I saw the progression of a self-proclaimed alcoholic who felt like she was going to die soon from the illness - and physically she was very pale and unwell looking; so much so that she was seeking and willing to try anything including Ayahuasca, which is an entheogen similar to but different than LSD - and arguably being done in a ceremony setting provides a different container as well.

There's an opportunity after a ceremony to share during a talking circle. I can't remember if the woman shared during then or to me afterward, however she told me in the morning that she could feel like alcohol no longer had a hold over her. I saw her 3 or 4 more times over a 3 to 4 month period at ceremonies - and by the end she looked very healthy, her skin had a healthy pink tone to it - and she was beaming with energy compared to before.

Another experience to share related to alcohol and Ayahuasca: an ex-girlfriend of mine had gone to a few ceremonies with me. After her first ceremony she shared two notable things. The first was an insight from her family dynamics that she could see from a holistic level looking down at the structure, which seemed to give her great comfort, reducing her baseline stress. The second was she was presented or saw simultaneously two separate "objects": she saw alcohol and she saw social situations. She's Russian so perhaps the deep cultural aspect of alcohol that seems to go with her background, along with her family always immediately offering a drink to her as their greeting when she'd visit are examples of how deeply engrained alcohol and socializing were for her. After her experiencing that division separating alcohol consumption and social situations, she roughly said she no longer felt the need to drink when socializing - though she never had a problem with alcohol - she felt like whatever association and connection to alcohol simply diminished, arguably due to the clear division of the contexts; unlinking the healthy engagement of socializing from alcohol consumption.
