I certainly don't mean to undermine your intake totals; however, I know my husband was drinking more than that daily, as was I about 5 days a week. We both quit cold turkey without any problems - no adverse reactions at all. My husband was able to work every day quite easily. I know everyone is different, and I am not recommending you do something that you or your doctor thinks is dangerous for your health. What I am saying is that it would be great for your family, and the best gift possible, if you could be home SOBER with them for the holiday.
You mentioned you are waking up daily feeling like crap. The longer you continue to feed the monster, the more powerful and stronger he will become.
