Not only is it one of my favorite U2 songs, but I recently looked up - and only because I was absolutely desperate - tried this remedy for nausea:
Suck on slices of fresh lemon sprinkled with salt
Yes, it makes your face contort in a manner that has your "supportive" husband making fun of you AND tastes vaguely like the lemon-flavored Sour Patch kids candy (not a bad thing in my book). But, I swear, try 2 or 3 of these slices of goodness when you are feeling at your lowest and it gives you some temporary relief.
Word of caution: remedy does not work when you are starving and therefore caught in a cycle of nausea and low blood sugar. It just makes you retch more quickly.
Any other tried and true remedies out there?
