Hello,
Believe it or not at the amount you drink you should not stop without medical supervision. Boy was I surprised to find this out after I had already stopped. I did not have physical withdrawals but I was drinking even more than you, every single night also.
I got so tired of the hangovers. I forgot what it was like to feel good. I would be hungover from 8 am to 5 pm. Drunk from 5 pm until I passed out. It started to feel terrible.
What did it take for me to stop the past week? Visiting this site everyday for hours on end, reading hundreds of other people's stories, replacing my cravings with lots of food and sugary soda, and nerves of steel.
It's not easy, but if you can bring yourself to focus on the positive, such as not being hungover every single day, it makes it a little easier.
Challenge yourself to two weeks.
