Suggest Therapy For Persistent Sickness With Insomnia

My mum has pulmonary chronic disease and gastric cancer which has spread into liver and other area of her body. She has been caonstantly sick for the last three days with no sleep at all. she can not lay down (each time she attmept to lie is sick although she needs rest and is totally exhausted. Nurses are visiting a few times each day. the macmillan nurse is on holiday. Mum is at home. When she is sick it is totally black. Nothing (not even water is staying down.) She has has somehting fitted to her chest to help the sickness bit it hasnt worked and each nurse that comes in provides a different type of injection that doesnt work. We know that she is probably in final phases but we want her to have a bt of peace. We are waiting for doctor to come out again but have to wait six hours! Any suggestions on how we could possibly make my mum more comfortable?
