Hi Twofish, my wife tried a bunch of different things. Some worked better than others:

EEG neurofeedback - worked great, but took a long time before results were noticable.

Diet - has a strong impact on her seizure threshold. Currently a low glycemic diet is working best for her.

Regular sleep pattern - has a strong impact on her seizure threshold

Acupressure - no noticable benefits after several months

I listed what I could find on alternative treatments in the chart linked below in my sig.

My daughter is currently GFCFSFCF and is using a natural hormone. This has all been done without doctors orders. The neurologist put her on gabapentin, however my instincts are that this did not matter, and before she is too far down the line with it, she is cutting back, ever so slowly and remain seizure free. My belief, is that since the seizures came on in her 14th year, that it will be controlled with nutrition. I don't want to call it a diet, as it is just a better way to fuel her bodies needs. In my opinion many neurological disorders could be controlled by giving the body the proper nutrients. If only we could find doctors that have complete knowledge in this area.
