David, my energy level improved SUBSTANTIALLY after I began eating regular food (mostly chicken,beef & pork no bread, potatoes, rice or other starchy stuff.) Now, it could have been a direct result of the food intake, or it could be that I was far enough out from treatment that my body was recovering anyway.
I also began to respond to treatment for post tx depression, so that could have been a factor also. In any event, things are much more 'normal' after I returned to eating and quit depending on the liquids.
