will drinking pineapple orange juice the next day make you sick if you leave it out overnight?!

I wouldn't recommend it because bad bacteria and germs can quickly start accumulating in any food product left out over night, especially those that should be properly stored or chilled. I'd say it wouldn't make you sick, but you may not feel too perky.

I've done something similar.

The pineapple-orange juice should be okay to drink the next day. At work I usually drink a carton or two of unrefrigerated juice over a time span of ten hours and I've never gotten sick.

You just never know. Honestly the citric acid is so high that it is probably fine. If it were me I would just smell it and take a little sip... if it tastes o...I would drink it, but you never know about bacteria

Mix it with a little alcohol (rum) and it will be fine, You can use the juice and get a light buzz too.

It should be absolutely fine. I've left juice out longer than that with no problems whatsoever.

you'll most probably get an upset stomach coz you left it out
