Well, i suffer from a nasty combination of Trigeminal Neuralgia and Panic Anxiety disorder, so think about pain medication and anxiety meds... you can see why i was a little loopy, I can't take the anti seizure medications otherwise it probably would have even been worse.

Anyway,after doing lengthy research on the subject post cleanup... and trying to find a way to deal with both I came across a combination of things that helped immensely.

1. was getting back to the gym and getting my body to recognize its proper functions, which was what had held my Panic Attacks at bay from 17-21 till i stopped being a gym rat and got depressed after my father died. Exercise also releases endorphins which help relieve the stress that causes panic.

2. Was cognitive behaviour therapy and changing my outlook on life from the nihilism i had acquired through the years and back to my old optimistic/progressive thinking self. Learning to let go of anger and hatred and channel that energy into positive functions.

and 3. the one you asked about... the Diet.

Trigeminal Neuralgia, in the form I have, like many illnesses is caused by chronic body wide inflammation. Being over weight does not help that either.
So, to counter both the inflammation and the weight gain... i went with a drastic approach. In the transhumanist and longevity communities there is much research being done into CR diets. CR standing for Caloric Restriction. Essentially what it entails is figuring out how many calories your body uses on an average day, and reducing your intake by 40% of that. so say if you went by the guidelines of a 2000 calorie a day diet as the FDA currently recommends you would reduce it to a 1200 calorie a day diet. Each meal eaten is eaten with its nutritional purposes pre-thought out, no fast foods, no high glycemic carbs, very little sugars... no simple sugars, nothing inflammatory. Lots of vegetables, lean proteins, garlic and hot pepper, olive oil, peanuts, still low fat but ingesting needed fats, and using proper supplementation to get any nutrients you may not be eating.

Right now i eat between 1000-1200 calories a day, the wife is eating about 800-1100 and we jog 5 miles a day (well... she cannot jog for at least another week so she will have taken 2 weeks off... but she has been at the gym walking a few miles a day since day 4 of her recovery. (never took a single pain pill)

IT has had many bonuses, it has regulated our seratonin levels, we have both lost amazing amounts of weight (when i started i was 188 i am 162 as of this morning... this diet started on Dec 2nd... she is down from 128 to 115) we have been sleeping better and waking up not groggy, our energy levels our up.... and my pain has gone away... entirely.
