I am sorry you are going through that. Really awful. Credit to you for tracking the symptoms so closely. The cyclicality of the nausea in your graph is interesting. Personally, I find cyclic vomiting syndrome is underdiagnosed and exists along more of a spectrum than generally assumed. As others have said, there is often overlap with migraine spectrum and central hypersensitivity. An underlying trigger such as a GI infection in predisposed individuals can 'turn up the volume' of normal enteric nerve signaling. This ultimately describes a lot of functional GI conditions. With central hypersensitivity, chronic pain, chronic migraine, and cyclic vomiting, one of the goals becomes resetting the sensory nerve volume back to a normal level. Meditation, therapy, etc., can all have a role. Often, antidepressants are often used at lower doses since they modulate peripheral nerves too. FWIW, you may want to ask your current primary or GI/neurologist about cyclic vomiting syndrome and whether to trial a TCA (first line treatment, amitriptyline has the most evidence)
