After the last SY, it usually takes three days to return to normal level. It seems that you are full of energy, so don't worry about your memory. It's just that too much SY will make people tired, affect their study and lead to poor memory, but it doesn't really affect their memory.

If you want to quit, you must make up your mind to throw away everything that stimulates your desire, and you won't move without looking at your hands. Once a week, your age will not affect your study. If your energy is still impaired once a week, extend the interval.

You can't give it up. Being too persistent will give you too much psychological burden. This is a person's physiological need, and you will think of it when you are full. Otherwise, you are not a normal man.

If you overdo it, you can do some exercise. Exercise can strengthen your physical strength and keep you energetic.
