Can you not move carriage anymore?
Try a bus down the length of Ireland on a Bus (not an express) in the wet with the smell of Vomit and salt and Vineger crisps.
Some people like them, they give me heartburn something rotten*, so I'm inclined to believe the crisps are as responsible as the motion for the vomit.
* Except Monster Munch.
Still not as bad as a short Swilly Bus journey in the 1980's where it smelt like exhaust fumes were coming in through the floor.
