I lost taste for whiskey around the time I turned 30 on its own. It kind of makes me feel like puking now. Strangely I am kind of developing a taste for moderate amounts of specific beers and beer used to make me feel like puking earlier. Taste for occasional wine stayed as it was.
So could it be some hormonal change? Something like this drug induces maybe?
Also, when I was younger my food intake was more automatically controlled. I didn’t have to watch whether I had eaten enough, unlike now when I often have to tell myself that it’s enough now.
