I eat everything I want at the moment, within reason and to the intuitive knowledge of what is good for me.
If I sometimes eat or drink what is not good for me, and what seemed to me to be dictated by an intuitive message, I feel not very well. This experimental knowledge is useful for another similar case. Thanks to such examples, I learn to distinguish intuitive (supportive) information from conditional, based on "I want" more than "I need".
When I feel worse after consuming anything, I go back to the moment when I "wanted" this food and / or drink and I feel it again to look at it with new knowledge, after the fact. I am analyzing a signal that I considered intuition and which turned out to be false. Comparing this situation with others, where I chose well for myself, I have a reference point later, according to which I make further, more useful decisions.
