Hi caramani, and welcome in
I never used to have nausea much pre-fibro or since fibro. Nux vomica D12 (homeopathy) seemed to help me then.
Like dizziness maybe a tough one to pinpoint, so it may need trying a lot of the routes that help people
It got severe every time I tried to move/walk after my jabs triggered what I now know is MCAS. My MCAS supps (Bruce Hoffman) helped with all the new symptoms, but I can't pinpoint which one of them may have helped specifically nausea. However comparing with those I was taking before the jabs anyway, it might be: EGCg, luteolin, silymarin, ellagic acid, magnolia/honokiol, feverfew/parthenolide. Looking at their connection to nausea in these cases it'd seem EGCg, luteolin and silymarin are unlikely, as they can have side effects of nausea, whilst
magnolia and
feverfew are used for nausea. Ellagic acid I'm not sure, may help stomach acid problems, despite it being an acid itself. Ginger is another one for nausea (e.g. in travel sickness supps), however one I don't 'stomach'.
From what I've read of fibromites with nausea, I fear you may be stuck with it if you don't find alternatives to your med - other meds, or supps, so I'd try out all you can get your hands on.
Also, nausea is of course a common side effect of meds (even aspirin and acid reducers like famotidine) and supps, as I've just shown, so I'd have a look at those first. In the case of acid reducers it may pay to reduce acid triggers in your food instead of taking the med. If you are only taking it because of the nausea, then I wouldn't continue. Peppermint may prevent people taking famotidine from getting nausea. But for me anything minty causes some of my biggest hyperacidity problems. My own experience is that most meds I take just suppress symptoms without curing them, whilst causing side effects which make everything worse.
