Ultimately, the taper schedule is going to be based upon what you can tolerate, as you're handling it yourself. In most cases, I would kind of balk at someone telling me that they are going to taper themselves, but apparently you have done it and I congratulate you for it, as it's pretty tricky. For me, it was so tricky moderating/tapering simply because because of Alcohol's dis-inhibiting effects. This often lead to what in my mind I termed "just this once" in regard to increasing the dosage of my taper schedule.
It has been a long time for me now, but back when I was in college, I would routinely consume 750ml hard liquor and maybe a half-pint on top. There was absolutely no possible way for me to taper myself. My self-control simply wasn't there. So, I ended up going to the hospital to detox and this was the best decision I could have made. It was truly a breeze. I laid in a hospital bed for several days with a Lorazepam (Ativan) drip. They slowly titrated the Benzodiazepine and I was out in less than a week. It was just the polar opposite of the pain, misery and constant failures of my own attempts.
When dealing with Alcohol and other sedative/hypnotic drugs like Benzodiazepines and Barbiturates, my interpretation of Harm Reduction leads me to almost universally request professional, medical care. I am speaking only of cases in which large dosages and dependency are in play. There is always the likelihood of experiencing a seizure when withdrawing from these medications and you can almost completely mitigate this possibility by checking yourself in. I know it's embarrassing and not your first choice, but in my opinion, it's your best choice.
Also, you mentioned that you had been drinking this much for about two weeks. That may seem like a short amount of time, but I don't want you to potentially misjudge how severe your withdrawal might be. If you are not already aware, please check out the provided link regarding a phenomenon known as the "Kindling Effect". In short, each time that you become dependent and withdraw from Sedative/Hypnotics including Alcohol, you will become dependent more quickly and the withdrawal phase will become gradually more severe. I speak from personal experience that this applies to Opioids to a certain extent as well.

I understand that you're planning to quit drinking, but I also want you to be aware of the fact that Alcohol inhibits your body's levels of Vitamin B1 (Thiamin) pretty severely. This deficiency of Vitamin B1 is believed to be the primary cause of Wernicke-Korsakoff Syndrome, known colloquially as "Wet Brain". It's basically a condition that will make you permanently retarded depending on the severity. I am in no way suggesting you have this, but I believe it's important standard information for any chronic Alcohol user. Here's a link expanding on what I've said:

Lastly, this bit is personal. Hiding drinking from you family is one of the hardest things that a person can do, especially if said family is already on full-alert and expecting bullshit. Instead of trying to taper, which is a noble cause, and getting in big trouble with your family, you could stand up and tell them that you are all done, that you love them and that you are making changes in your life and going to try to detox at the hospital. You can escape with some dignity and some confidence from your family in the process. This is just me dude. I don't know your family or your situation, but that's where I'm coming from.
