Well, the brain is very powerful. You did the ritual of viewing the bottle, opening the bottle, pouring the wine, drinking the wine. Hell, it's even called "wine."
After all you've been through, that is a traumatic thing to have to relive. A lot of control issues at play.
I agree, I wouldn't try that again - especially since you were recently romanticizing Chardonnay.
edit to say, yeah, the painting tonight is probably not a good idea. Good call!!
