Did I say Snails?

Took a visit to the medical centre at 2:00 am last night.  I woke up with my eyes stinging and without realising it, I started to scratch at them which then got unbearable very quickly. The prepared traveller reaches for his Visine which I did have and washed both eyes but they were closing over. Then the throat constrictions started and breathing became difficult.  I spent an hour in the infirmary, they injected me with Roids, I swallowed anti-histamines and breathed through the nebuliser mask for an hour. We have to buy the mask and a ventolin spray. This has all been added to the bill at the end of cruise, using US dollars.  No phasements. The doc said it could have been what I ate but could also have been something in the air conditioning.

The eyes have it
