Those who practice Brahmacharya generally complain that they get mental fatigue owing to continence. This is only a deception of the mind. You get sometimes a pseudo-hunger, whereas, when you actually sit for dinner, you have no real good appetite and you do not take any food. So also, there is a false mental fatigue. If you observe Brahmacharya, you will have immense mental strength. You will not be able to feel it always. You will manifest it when the occasion arises, in the same way as a wrestler manifests his physical strength in the arena, though he feels as normal man in ordinary times.
If you get mental fatigue on Brahmacharya,be wary,it isa mental deception.
