I think you probably have to do the antiemetics like Zofran and Emend for the best relief, but I have used homeopathy in conjunction with them, when the nausea, vomiting and acid got too much. Although they didn't totally relieve things, there was always an instantaneous sense of relief from the symptoms. I considered seeing a homeopath who works with cancer nosodes as a way to try to prevent it coming back again, since there has been some work in that area. I know if you were to ask my husband, he would be thankful for the relief homeopathic has given him. I've been a self prescriber for years, but at times with bigger issues have seen a homeopath for higher potency use. We use carbo vegetabilis for gassy nausea, ipecacuanha if he's actually throwing up, and acidil (combination) for acid stomach. Also use sinusalia at times for full sinuses, which create nausea and vomiting for my husband, but he's more likely to take benadryl for that. I think part of the big fluctuation in weight can come with dehydration too. I've seen my husband go in for a few hours of hydration and walk out 3 lbs heavier. During the 1st round of chemo/radiation we used zofran, but never quite got a handle on it because it got ahead of us at the onset. During the 2nd and 3rd rounds of chemo, he used zofran daily and added Emend on the day of chemo, and the following two days. The difference in nausea and vomiting was astounding, and his weight didn't fluctuate as wildly as round 1. He was never a big person, so he just doesn't have the weight to lose.
