Fighting drug and alcohol withdrawal

I have been on a long journey over the past 7 or so years. With addiction to marijuana and alcohol. I have developed drug induced psychosis. I had social anxiety and depression. All of which have been resolved. I have been off marijuana for 12 months, but have used only lightly for 4 years. I used for 5 years everyday in massive amounts. I drank every day for about 3 years. Now I drink 4 days a week on average between 4 and 8 (budweisers) as an international standard for alcohol content. For a lot of the time I had a problem with pot, I was experiencing seizures almost every time I used. (clonic) simple partial. With the occasional semi-conscious episode. Now I get Tonic seizures at night and rapid unpredictable mood swings, that only seem to affect me interally.(feel very agressive toward no one or nothing in particular).I get myoclonic seizures randomly.Could this be explained by my current level of alcohol use. or is there something neurological that requires further investigation?
