For anyone who had never been on an intergalactic ship, the first days were a real hell, getting used to the gravity-sensitive suit that allowed the artificial gravity devices to work perfectly without the crew members' bodies suffering in the slightest was difficult. The sweating, perspiration, and even headaches due to the effects of artificial gravity, which was not as perfect as everyone would like, generated physical imbalances.
Getting used to the hatches and weightless tunnels that connected the different decks and areas of the ship was difficult and required a habit so as not to end up flying aimlessly inside. But the worst came at bedtime; insomnia was the least of the problems, and the narrowness of the cabins and the sleeping cabins were something that even the very prepared cadets of the officer school suffered, and even more so did they suffer. They had not had weightless situation training.
