I'm feeling pretty yucky too - I sympathise!
I get by with Fruit Tingles lollies and those sea-sickness bands you get from the chemist! Fizzy drinks seem to help too. Gingerale (or anything with ginger) is supposed to be especially good - not that I've tried it personally.
I have troubles with everyday smells - I can't imagine how you're coping with the nail chemicals - I'd check with your GP/OB about them.
