Hi there I'm going to tell you what everyone else told me when I was in your shoes and now with hindsight i can guarantee that they were right:
it does get better!!
What's more you'll soon find you're getting a much better quality sleep and won't be waking up a few hours later.
Like turned said I find i need less sleep than before and I have more energy the next day.
Just be patient (no i'm not very good at that either
: ) to be honest the first few days are sh**ty but afterwards it's much better.
I hope you'll have more sense than me and not frequently relapse because everytime I did I had to go thru those first few days again
For every day further away from a glass of wine I find I feel better!
Hang on in there and keep posting!
