I took 100,000 units of Vit "A" daily, for 8 months, that Dr. relieved a problem I had that was treated with freezing with Liquid Nitrogen, Acid, and Electric Burning, for two years only to spread and grow worse. I still take a dose of Beta Carotene 25,000 units daily for the last 40 years, as maintenance dose. I also take 3,000 units Vit "C", time release daily.
My Pill boxes are running over.

Not too bad for someone that had to chew Bayer Aspirin to get them down.
In Life you do what you must!
