I think your neurologist should be listened too in this case as long as you feel he is a well trained and accomplished physician. If you have any doubts about that, you should consult your primary care doctor and get another referral.
The picture you present does not fit any neurological diagnosis and can certainly be from extreme anxiety. You know whether you are anxious or not, so you are the best judge. Give the medicine a proper trial and see if it works,and increase the dose under supervision.
If you want to start exploring some of the sources of anxiety, go to my masteringstress program (above link) and become a member.
Their are a lot of lazy docs out there..
Take care
