Nice going on three weeks!! That's a big victory. I know what you mean about Greek Yogurt. Tried it, didn't like it.
Went through the same thing you did with the hallucinations, injuries, etc. Last time, I honestly believed the Marines had taken over my apartment to spy on my neighbors across the street. They had rigged up all kinds of electronic equipment all over my apartment. They told me there was a federal law that allowed them to do this. And believe it or not, that wasn't the worst of it. Got pretty scary.
Best advice I can give you is to be good to yourself. The first month is hell. Take it easy and be patient. Like many people have said here on SR, make a plan and be prepared when those thoughts of drinking come up. Don't be caught off guard if that happens.
Best of luck. John
