Hi Blue...So sorry to hear your plight. I have only been on this horrible journey now for under 12 months, but have said goodbye to a few "online friends" and acquaintances I have met along the way at Hospitals and Oncology. This is a very cruel and heartless disease.Originally (untreated) I was given 3 months to live, but now have been given a brighter outlook with the help of Chemo and diet.I have been able to try to "maintain" my weight by learning how to combat some of the side effects of the Radiation and Chemo.Eating/Drinking smoothies is a good way to help (especially when there are some many recipes available (We have even made up our own!!) and to combat any nausea I use ,not only the prescribed" Pramin tablets, but also Ginger Tablets (high dose Travel ones) and drink Dry ginger often,also LOTS of water ( sometimes with a bit of Poweraid for the taste)I also credit "Astragalus and Wheat Grass Tablets" as a supplement to my immune system.These HAVE been approved by my Oncologist Pharmacist.I hope some of this helps. I have got a lot of links that my Daughter has researched if you think that may help. Now....for yourself...please find out if there is someone, somewhere that you can talk to about all of this.Either paid or free advice (maybe through your local Information and support Centre...Doctor..Oncology..Palliative care..Australian Cancer Care (give em a call..their good)..or Cancer support Centres. If you can learn to be stronger I`m sure it will be easier for you to comfort and support your Dad and Family.My wife has just gone through 4 months of regular meetings with Councilors,and she recommends it (and I am her Carer and have been for many years). I hope you Dad starts to feel a bit better and if there is anything We can help, please dont hesitate to ask.
