I think CBT has definite benefits but also limitations.....for pure anxiety symptoms it helped me greatly. When I was really suffering mentally and physically from my sleep disorder, it was a joke to think that CBT would do a thing. i was suffering not from my outlook about my sleep disorder but the pure symptoms themselves. had mild friction with my husband and my psychiatrist on that initially because I wasn't doing my coping techniques, it took a while to drill into them the difference between my anxiety and my physical illness
