You were buzzed. You went on social media and made some comments that you would never post if you were sober. The next day do you run back and delete them all?
I mean state of mind, judgement, and especially impulse. That's not to say caffeine has a huge effect there, but I could see it resulting in people posting things they may otherwise think 3 times about before moving on.
And another user mentioned ambien, so there are definitely more options.
That's probably got more to do with the sugar high often associated. Chocolate, tea, cola, and more contain caffeine. I just have simple caffeine tablets on my desk.
Zolpidem* and others are not over the counter medications, at least not here. You need a prescription to get them, it's kinda sad thinking how many people depend on medication to then run into situations like this.
*Ambien is just expensive Zolpidem with a brand name on it
