No, I don't remember where I read about it, but it wasn't on CZ.
I've had that 'drugged' feeling before, but it was just a few isolated instances, not a constant feeling.
I'm wondering if there is an OTC test that you could buy to test yourself. Not sure if it would show up on a breathalyzer, but probably on a blood test. Something to research later...
I wouldn't focus so much on the alcohol aspect. You should just follow all the great advice given here to get the candida under control and do a parasite cleanse as well. Are you taking DE? That's an easy addition to whatever you're doing now.
