I certainly do not want to go on eating MSG! But since it is everywhere, sometimes we ingest some inwillingly.
When you travel around a lot, it is not always possible to stick to a diet. This has terrible consequences.
Not only physical. It destroys a person's optimism completely to be repeatedly poisoned and to feel there is no way out of this.
I am trying to help. Not by saying that you could go on eating rubbish, but by trying to find a way out of despair.
