I have picked up a nasty dry cough since arriving Athens. That’s over 2 weeks ago?

I was exhausted from the night travel train and bus, and the sudden heat probably triggered it.

It’s killing me slowly, the cough will just start in the middle of the night, and cough myself awake. Tried local cough meds, over the counter cough candies, none seems to help. Hope this doesn’t continue much longer, cause I’ll have to seriously get this heal.
