Sometimes a couple beers or a drink is ok if I am overwhelmed, but many times when I've drank when stressed I've drank too much and have acted stupid and what not...so I try to be careful about drinking when I am stressed.

And for a while I was getting drunk just about every day to cope with stress and untreated PTSD symptoms, but yeah in the long run it didn't really make me feel much better....I do however find cannabis very useful and have never gotten out of control under the influence of that like with alcohol so that is more my substance of choice.

But yeah over time I have cut down a lot on alcohol consumption, and that seems to be working better for me. Anyways I can't tell you what you should do, but if you use alcohol that way just be aware there are risks and it can get out of control...sometimes even if you do think you're using enough caution. But I really don't see much wrong with having a drink or a beer or two(not 6 beers and a drink or more) if you've got something on your mind just to kind of relax and perhaps be distracted with less serious thoughts for a while if you can handle that.
