I began seeing a personal trainer, adjusted my diet, and saw a cognitive therapist, and most of the debilitating
symptoms went dormant. I still suffer from residual symptoms of anxiety: excessive sweating, IBS, and occasional insomnia. From what you are saying, the sleepwalking may be also be a residual symptom of the anxiety?
I was also on Trazadone for a while, to help with the insomnia. I did not like it at all, especially when I learned that it was not a sleep aid, but an anti-psychotic.
