Zoe,
I am so sorry that your mom has this horrific disease, My Husband just passed from it on March 7th at the young age of 42... Our journey with the disease started last September when I rushed him to the hospital with Adema and swollen tummy.. They had told him then that if he drank again that he would die... They were right.. He stayed sober for 64 days then started drinking vodka again, on Janurary 12th I rushed him to the hospital due to vomiting blood, he spent 3 days in ICU and 4 days in the hospital, they told me then that he will not live but would never give me a time frame---they dont want to do that with this disease, I am assuming that it is becuase it is such an up and down disease.. I had hospice come in to the home, I would highly suggest that! they help you understand things so much more---- although my husband was dieing he would sleep for 3 days, then he would be up and moving around the next three.. it is a very very confusing disease-- for the caretaker.... I guess what I am getting at is, my opinion is that you should try to go see your mom if possible.. the last month he was alive his edema and swollen belly went away, and the hospice nurse told me that sometimes this just goes away at the end for no reason...... I have heard of people living longer then the doctors say and have heard of people not-- you just never know.. In my case it took my husband at a young age, and honosty liver disease and Chirrosis is a horrible disease to have, it is a roller coaster ride and my thoughts and prayers are with you and your family through out this!
Take Care
