Just be careful - there is going to be a downside from drugs to make yourself awake, drugs to make you sleep etc etc!
Has anyone ever been so bad they weren't able to get on the plane? I've seen a few car crashes in the airport
Once our mate was so bad (believe it or not just on alcohol!!) we found a discarded wheelchair, put him in it, the security at Ibiza airport actually thought he was disabled and were helping us in the lift lol!!! TBF he did look very very ill!!!
I passed out at the Madrid airport gate, they took 30 minutes to wake me
