In Canada, you can get a drug called Diclectin which has been prescribed for decades and is the best thing ever (possibly what pokeyac mentioned?). It's basically a B-vitamin and the stuff in some allergy medicines that makes you drowsy, so people often make their own.
Apart from that, eating ALL. THE. TIME. (seriously, if you feel hungry it's TOO LATE) is a good one.
I also wanted to mention that my initial blood work came back showing signs of hyperthyroidism, and my doctor told me that it can cause more severe nausea. I won't know if that was the case for me until my follow-up blood work comes back and I am (probably) put on medication, and I'm not saying it's necessarily the case for you....I just didn't know it was a possibility until the results came back, which is why I mention it.
I hope the yuck eases up soon!
