I am hesitant to give advice because of my history. If I admitted to 6-12 drinks a day, the actual amount was quite a bit more. I too was terrified to detox, because I knew something I wasn't telling, the actual amount was quite a bit more. I had a seizure.
Honesty is of the utmost importance to me for maintaining sobriety. I got a chance at being honest when detoxing. I didn't take it, luckily I didn't die as a result of my dishonesty.
Medical advice and supervision can very important when detoxing. A lot depends upon the actual amount of daily consumption.
