PTSD here, and alcohol DEFINITELY aggravates my anxiety symptoms. Once I cut down my alcohol use, my life became significantly easier. However, I usually don’t see this encouraged when I look online. I now drink maybe one or two drinks a week/every two weeks, and just socially, and anything more than that will start to aggravate my symptoms. But this is just something I noticed on my own. Generally ,society and social functions seem to encourage drinking to relieve stress.
