I'm only on my first fill and I have no restriction, so I'm not speaking from experience, but I do know that in the morning, all of my body is kind of swollen. Like, my rings are super tight in the morning and my ankles are a little swollen and my face is puffy. Could it be that our insides get swollen too and that's what causes morning restriction? By nighttime, my rings are loose, my face is not puffy, etc. Just a theory...
