I started in high school and finished around the beginning of college entrance prep. There was no clicking sound from my jaw, it was easy to align the midline, and I no longer had to put strain on my teeth or jaw, so it was really nice.
But once I started studying and working, my posture got worse, and maybe because of stress, even when I wore my retainer I kept clenching, so it was hard..
Even if it’s annoying and difficult after finishing orthodontic treatment, I hope you wear your retainer properly...ㅜ
