Is ketogenic diet helps tread epilepsy?

Hello everyone, About 7 years ago I had 3 epileptic shocks, after EEG test, magnetic resonance, doctors said that the brain function is normal. The shock started with a feeling in my right hand as an electric shock, going through my arm until reaching the neck and resulted with unconscious. I started to use Tegretol 200 mg, twice per day. After 3 years of using everything was normal, then I skipped the therapy and use alcohol for few days in a row, then I had an epileptic shock again. After this I am using the medicine, until 2 months ago I was feeling good. Sometimes I am consuming alcohol and skip the therapy, but was fine, but not for few days in row. Few of the shocks happened during а masturbation (self-satisfaction). In last 2 months sometimes I have a feeling in my hand like the epileptic shock is "preparing". So I am wondering what can happen, and also I am looking for a natural treatment. This is my diagnose: G40.20 Symptomatic epilepsy associated with localization (focal) (partial) and epileptic syndromes with complex partial seizures without the mention of resistant epilepsy. Can someone share opinion and experience with ketogenic diet as a treatment for epilepsy? Is there any specific meal plan for ketogenic diet to treat epilepsy? Many thanks in advance. Viktor.
