What a great brother you are!!! Not every sibling would stick by the other ones side thru everything. Im sure he greatly appreciates you being there for him.

Now the key to this whole thing is keeping at least 2500 calories and 48 oz of water in him every single day. If you can get more in him that would be even better. Even 3500 calories isnt too much when his body is burning the calories up at such a fast pace. Keep getting the IV hydrations too, ask the doc to write a prescription to get it a few times per week thru all the treatments and for the first few weeks afterwards. It really does make a big difference in helping him to feel a little better.

Try to keep managing the pain. Your brother must communicate when he hurts so it can be adjusted to the correct dosages. It sounds like you have everything under control. Between getting that in order, getting hydrated and finally being able to take in enough calories he probably feels like a new man.

Keep up the good work!!!
