complicated case

Any knowledgeable opinion about this situation will be duly appreciated.
Patient, female, in her first 60s.She had showed some tendency to vomit when either not eating in her usual times or when eating too fast; when the first would vomit clears, lightly yellowis viscuous liquid, in the second regurgutate the food in a short time, from five to fiften minutes. She would crave for bread and mil, liked well met but have some trouble digesting it, same about eggs. Recently after had been well enough for a time in somewhat sudden way one morning and after fasted the prvious evening was with low spirits, then vomited before breakfast and differently from usual that would want to eat few minutes after having had one of this kind of vomits, was totally inappetent. She accepted some milk but then vomited it after a short while. She was alos refusing then any other liquid. Considering this she was given Phosphorus LM 0/1, and from here things got complicated fast, Phosphorus didn't act heaingly but increased vomiting and appeared a little diarrhea like situation, her practitioner considered that this asked for Arsenicum Album (all potencies mentioned here were LM), and as things just kept the same, it was given the 0/2 after the 0/1 didn't work; by then there was a total anorexia and adipsia, and after interrogating again the patient and some of her relatives the practitioner came to the conclusion that her constitutional remedy would be Pulsatilla, was mdicated with it but just presented a "probing" of same Pulsatilla, and ina strong way as the practoner said he was between trying Silicea or Nux Vomica, again he tried to get a more complete history of the patient and more than the Silicea image came up, now with the opinion of other close realtives and the way the patient was behaving then, that more than Pulsatill she had characteristics of Nux Vomica. All this time the main troubles kept being vomits that by now had came from clear matter to a more bilious one, clearly bilious, and the total refusal to eat and drink; still the little she was cajoled to have and could go through the vomit, would produce some excrement, formed, which along with any other symptoms discarted a vowel obstruction. Being an antidote for Puls NV was tried, but almost immediately poduced a typical NV vomit with a lot of wretching, difficulty to bring up the vomit and projected this with force. So, it had to be changed again this time for Sulphur to stop that kind of vomit and hoping it would set what would be the right remedy at last as happens with Sulphur. And effectivelly Sulphur stopped the NV symptoms and pointed, again to Arsenicum... And so again was tried Arsenicum, and again with bad results, just increasin the intensity of the symptoms without any other change. Was then thought that in this case where the remedy was "probing" itself in the patient was to try to break this situation with a higher potency. I tworked but aprtially, the vomits were reduced in intensity and frequency buta fter a promising but short time improving of spirits and general beahviour, and acceptance of some liquids, water mainly, typical of Arsenicum, in little amonts, and some, very little mik, the adipsia, anorexia and lack of desire to move any much pervaded the situation again. by now the patient was already quite dhydrated and with the vomits she had to be hydrated intravebously. Her state of mind has changed towards a kind of mild dementia, with not putting attention to people andbeing most of the time sleeping , with eyelids half open part of the time, and just lying down. Though she would react to sudden sounds around and some things that would catch her interest, is not communicating. Her demeanor is nonchalant,indifferent. The situation, due to this truble of not wanting to eat and drink and the vomiting has worsened the situation much and fast. The alpoathic school proposes an aggressive approach, injecting antiemetics, forced feeding by a gastrig tube and subjecting the patient to a battery of imagery tests. The patient always manifested her dislike by this kidn pf proceeding and npw that she had to be hydrated in emergency showed great distress about it. Yhe homeopathic practitioner is by now wary of intervene more, he manifested that he was weary to prescribe what he saw like an option China, as this could just complicate things more. He consulted with other colleagues and all coincided int hat they couldn't see with enough clarity the situation as it has developed and why has developed like this, where could had been the point where the treatment became wayward. The patient in just few days is in imminent death peril and she refuses to try the allopathic option. Could someone please help with his or her ideas? Thank you in advance.
