hey My grandmothe went through the same thing about 3 years ago... it's sad to say...but The doctors gave her 6 months to live and she lived for the next 3 weeks after all the same things as your grandmother... I loved my grandmother to death.. she was my best friend... I lost her last year and still miss her to death.. I miss her wisdom and her ability to spoil me... but my advice is to just enjoy every minute you have with her.. because she was doing fine one week and the next 3 weeks she was gone.. she also was a smoker.. she was trying to get my aunt and mom to sneak her cigarettes while she was in the hospital.. but I pray that you at least spend as much time as you can with her... because they are not going to be here forever... I think my grandma loved me more than her own children...hahahahha... life is tooo short...enjoy it while you can... take care
