It must be off

I've been drinking some cloudy cider, which will go unnamed, and it is clearly (no pun intended) off or what ever cider does in that respect.

The thing is, as a child, I used to drink vinegar and that's just what this tastes like. Now when I say drink vinegar I'm not talking loads of it I just mean I'd have a little. I liked the taste.

Now I'm pretty sure now that I should stop drinking this. I've had half a bottle and it's given me a heck of a head ache.

Just one more sip. Pinkie swear
