You do need B vitamins but they do not prevent seizures alone.
But the bottom line is the following-
You have a history of DT's therefore you are high risk for more DT's upon withdrawal.
The standing orders we used in the Jail Clinic in Houston were the following:
Librium beginning very high and tapering over two weeks is crucial to preventing DT's and early seizures.
Phenytoin loading dose immediately then maintenance dose. This is an old line seizure medicine.
Thiamine to prevent brain damage- which is given by IM injection 100mg/day before anything else to prevent Wernicke-Korsakoff Syndrome.
B Complex tablets which is the source of Niacin, twice a day, for 10 days, then daily.
Multivitamins with minerals and trace elements twice daily for 10 days, then daily.
Balanced plate lunch diet three times a day.
Daily physical examination for neurological status, and close management of concurrent chronic diseases (usually Diabetes, COPD, Hypertension, Liver disease and Heart Disease as a base-line).
Observation, supervision and on duty medical providers 24/7.
Immediate referral to Ben Taub General Hospital for complications and medical or surgical emergencies.
This is NOT a prescription, but is a functional outline of one protocol that worked 100% without seizures, DT's or fatalities over a year period that I worked there.
Absolutely positively do not try this at home.
That is rock solid, do not even think of doing it at home: you need prescription meds, close 24/7 medical attention and care to prevent seizures and DT's which is a medical emergency and kills.
The best treatment for the seizures and DT's of alcohol withdrawal is prevention. Prevent them during the fragile period and you do not have fatalities. Allow them to begin and you have serious problems.
Rock Solid Advice- you should not only not go through withdrawal with your history at home,
you should not do it in any hospital or clinic that does not do this every day with good success and outstanding prevention of seizures and DT's altogether.
Since this is your life in the balance: find the in-house treatment facility which not only treats but totally prevents the life threatening complications of alcohol withdrawal.
They exist. It can be done. Do it right and live.
Good Luck on the rest of your life and remember Hoss, God Loves You. That makes a difference.
