So sorry to hear about your poor Mum. And also to you with what you'r going through as it is the hardest thing in the world. 

My Dad died 23rd August this year. 4 months tomorrow to be exact! He had been on chemo 2 years previously but in May this year once the cancer spread to his brain then palliative care came into place. He deteoriated quite quickly and obviously some of his symptoms may have been brain related. Weeks before he died he was quite restless, tugging the bed sheets and moving his feet up and down the bed. He also always had his eyes closed even when awake but that may be down to the brain. He could no longer swallow food without choking so the only option we had was to feed him things like yoghurt etc. Then we had to syringe his fluids into his mouth because he couldn't drink with choking. Then about a week before hand we started moistening his mouth with a wet cloth as drinking through a syringe started becoming difficult for him. Then 3 days before he passed away he had an energy burst where he had his eyes open watching and listening to us and it was great to see him like that. Then the following day he slept all day without wakimg, the same again the next day too. Then on the 3rd day of sleeping I went to see him. I knew immediately he had a matter of only hours. Everyone's different but with my dad he had a high temperature. I always thought people would go cold but thats not true. He was sweating and clammy, so a cool flannel was put in his forehead. His eyes were rolled as if they was half open and a loud rattling gurgling sound was coming from his chest. As soon as this sound starts then death usually occurs within 24 hours. But not everyone has these symptoms. Also I noticed his urine looked like tea. Which is another symptom to look out for! My dad's skin colour also went a light grey.
