Uuuugh smoke. My sinuses get screwed up SO bad. I remember once my family got stuck in a smoking room at a hotel because the front desk gave our room away even after we told them we were going to be late from the beginning
not to mention we're diamond status at the Hilton but anywaaaay... long story short, worst. Night. Ever.
Honestly, if my grandfather can successfully quit smoking after ~60 years, other people can, too.
It's a pretty disgusting habit IMHO.
Not happy having sore throat right now. 
Bit late buuuut. My friend swears by gargling with plain lemon juice. Burns, but apparently works.
