Adult thumb sucking and pacifier use associated with anxiety?

Thumb Sucking: Adult thumb-sucking can definitely be tied to an anxiety disorder. In fact, the thumb sucking ; pacifier use could cause you to swallow significant air, making reflux symptoms worse. I would consider cognitive behavioral therapy to find out the cause of the behavior--it can lead to chronic fungal and bacterial infections of the thumb that could be "digit losing". The cbt will give tools to help.
