Baby_Sham, green tea is good, and add plenty of sugar :-) I know it sounds daft. but eating plenty will be beneficial to you now. (I was a 5 stone skeleton when I finally detoxed as the alcohol was my only source of calories at the end of 8 years of drinking daily) I drank to ease the anxiety at first, then I drank just to function in the morning by stopping the shakes.
It's ok to be embarrassed, just let it go - nobody is perfect and you are doing the right thing, right now. it is a cliche, but consider every day without a drink as an achievement and don't rush to a 'final goal', you will be back to yourself in a few weeks time and can hold your head up and get on with the rest of your life.
Just don't beat yourself up about what you did yesterday, a week ago or a year ago, just stay focused and be proud.
I am still an anxious person, but that's ok, you learn to know what to do to calm yourself down without automatically reaching for the corkscrew.
Keep chatting, and try to keep yourself occupied with small stuff at the minute :-)
