As far as being tempted to drink it -if my mindset is to not drink - I won't drink. My wife keeps her beer in the fridge, her wine on the counter and I know she has vodka stashed somewhere in the house. Besides, every store sells alcohol - I would have to live in a cave not to have it in my face.
Speaking on saving that can of beer for a memento - I collect rare and unique beer glasses and shot glasses because I have always had a dream of building a bar in my house.
Well yesterday I was at a thrift shop and they had some cool beer glasses. But now I can't buy them because I don't need them - that dream of a bar isn't going to happen. I also have alcohol related shirts and hats in my closet.
Quitting alcohol is more than just putting that bottle down. After 25 years of hard drinking, boozing has become my identity.
