Are you sure it needs to be "cured"? Lately I have been thinking that it's a blessing in disguise; a painful -but effective- motivator to improve and seek out new skills and more knowledge.
Yes, it comes with a side of depression, and that really sucks, but I've found if I'm deep in some tech I don't know, it doesn't seem to affect me nearly as much.
Could it be jut us getting restless? The feeling we haven't learned anything new or faced any new challenges lately?
