Try eating something really heavy like a big juicy burger. I'm not kidding, it worked for me when I was going through your same situation. One of the contributing factors to nausea is a lack of energy, so the burger should do the trick. Subway sandwiches work great too. You need to eat a lot though, it's the only way you'll keep your energy up to fight off the nausea. Also, if you're doing a low-level like a vnav flight or something else really bumpy down low, try sipping on the O2 mask from time to time. When you feel the slightest bit queasy, just hold it up to your face for a little while until the nausea goes away. Just hook that mask bracket hose clip to your SV-2 so it will hang down in front of you while you fly so you can grab it easy. You'll get over it man, trust me. I did. Might hit you a little bit again during PA's, but you should be used to it by then. Good luck, and don't sweat it man.
