Hi, Peace. The anger and body odor will go away very quickly when you stop drinking and the brain fog will gradually start to lift.
So the question is not whether to stop, but how to go about it. Like it says above, get a solid plan together because folks tend to fall off the wagon without one.
Also, I really recommend seeing a doctor because they often can give you a lot of help, and also check you out and make sure you're in good health. I was really embarrassed to tell my doc, but when I did I was pleasantly surprised to see that he saw alcohol addiction as a medical issue, no different than a patient having bronchitis. No judgment at all.
