For the moment, I recommend you get yourself to either a naturopathic doctor and/or an acupuncturist (TCM). If you can't do that, a stop gap until you can is ti try out an herb called Shatavari, which is helpful in cases of dyspepsia and acts much like the drug domperidone. Additionally, you may want to consider probiotics and enzymes.
Finally, try an elimination diet to see whether your food issues are due to food intolerances
