I have oral sensory problems. So it’s an oral fixation. Basically chewing and sucking on things calms me down and helps with my anxiety and sleep issues. At night I drink out a bottle and I sleep with a pacifier and I have a chew toy meant for people with autism that has a lot of different textures on it. I also like to eat dense chewy foods like Little Debbie Cosmic brownies and Ezekiel bread and beans.
