Catching up on the posts I've missed the last few days.
The "void" for me wasn't actually much of a void. If anything, when I was drinking I never felt that I had time to do anything. I was always either working or busy somehow. Or sleeping. I didn't really realise how much time drinking took up. The other half used to complain all the time that I was always rushing and never had any time to relax. It didn't help that we didn't live together so I was also trying to fit in time to travel to see him.
Now that I don't drink, and I don't need a lie in at the weekends, I'm actually just making better use of my time. Boring I know, but I now use my weekday evenings for stuff round the house and cooking or whatever, and the weekends are free to see friends or long walks or exercise.
