An update:
It's now almost a week ago since I started this thread and I'm now exactly one week sober. This time 7 days ago I was collapsing into bed in a drunken state and would wake up a few hours later feeling ill and full of self loathing and remorse. Now I'm about to go to bed simply because it's bed time and not because I'm drunk. And I'm looking forward to getting up in the morning with a clear head rather than dreading it, wondering how ill I'm going to be and how I'm going to be feeling.
Thanks to this forum for being here, SR is a great help and reading all the posts here in the past week has helped me get to where I am now.
