Nothing wrong with asking questions. But then be prepared for armchair quarterbacks to answer for the type of question the OP asked. The OP has a physical condition he is concerned about.

Medical diagnosis (in this case fatigue) is complex enough in person...expecting it to work via Internet forums is unreasonable and it delays getting competent help. There is no way to validate the source or quality of the advice you are receiving. All a person is getting is vague and nonspecific advice that anyone can write on the internet.
