When I was coming out of freeze (and just so you know, it's in a matter of degrees), my body was rythmically jerking for a few months. It's great that your husband is giving you tight hugs as that can help.
Remember that discharge is a way your body is letting go of excess bound up energy. As time goes on you're going to feel calmer because of it.
All in all, I think this is a wonderful sign Just Me. In time, your body will relearn to regulate again and you'll be able to manage more.
Take care,
