Specifically it was chocolate-flavored soy milk. I figured that would be "safer".

The experience of drinking the soy milk went roughly like so:

[pours the milk]

"Hmm. Maybe my eyes are playing tricks on me, but it looks ever so slightly opaque compared to dairy milk..."

[gives it a good sniff]

"...It smells like basically nothing. Just as I like it!"

[tastes it]

...

...

...

"...Yeah??? OK! I can fuck with that!"

[puts glass down]

"Well, it feels somewhat watered down, yet also a bit saccharine; and the chocolate flavor is clearly different from what I'm used to; but on the whole it's not bad, it's just different, and 'different' is exactly what I was expecting. Really, as a whole this milk is largely indistinguishable from a different brand of dairy chocolate milk I've had previously."

[gulps down the rest of the glass]

"I mean, you know, it's not like the flavor on its own is preferable to what I'm already used to — God knows this costs a bit more as well — but I would gladly only drink chocolate milk that tastes slightly 'off' if it means less animal abuse. This hardly counts as any sort of sacrifice."

[drinks two more glasses]

"Honestly, I take back what I said, this is just good. Why on Earth isn't this just the standard milk already‽ Why was this stuff just hidden away in some random corner of the grocery store, where I nearly missed it completely‽ I mean I know the answer already, I'm just saying it's messed up..."
