Thanks Maudcat. I was on day 6 and honestly it's the best I felt in a long time then I had a weekend bender and it just wasn't worth feeling so tired all the time.
I don't think I realised it but the difference is night and day but I'm glad I ignored the post work AV and instead opted to buy a loaf of bread instead of a bottle of anything. Definitely feeling a lot happier and sober me was productive, lunch is all sorted (a nice healthy lunch) and I've cleaned up a bit.
Reading this forum has helped too, a lot of what is said is positive and makes me think-tank yes, I can do this!:-)
