Why are you taking so much Cymbalta ? The literature says there is no benefit beyond 60 mgs per day. The high and overlapping doses you are on are as if you are struggling with life threatening severe depression, not headaches and insomnia.

Why is a psychiatrist treating you rather than a pain specialist or physiatrist or neuro ? Was the psych prior to the concussion ? Have you tried anything besides the Cymbalta ?

Gabapentin and even Lyrica have a better track record as off-label meds for headaches.

The literature I read years ago mentioned how low dose amitriptyline (10 mgs) before bed was optimum for head aches and insomnia. More was not usually better.

Just some ideas for you to consider.
