Our case study is similar. I, too, am 81 and have been told to take just one bottle of iron. If deficient in iron, why would't the deficiency continue to re-assert itself after one bottle? Unlike you, I have not had to have injections. I am trying, too, to fight depression and loneliness since my son died of pancreatic cancer. Suicide is appealing, because of my age and depression, but I do not want to demonstrate to my son's teenage grand-daughters that suicide is an option.
