I'm also really pleased to hear about your progress. Not sure about the anxiety one but on the insomnia one, let me assure that prolonged sobriety really helps there. There are some very practical measures we can take on it too. For me these include:
1. No caffienated drinks after 4pm.
2. Setting a regular bed time and waking up at the same time
3. Not using computers or mobile phones for at least 30 minutes before going to bed.
4. Wearing warm bed clothes and cleaning my teeth
5. Not smoking
6. Writing a gratitude list
7. Using an eye mask and ear plugs if I need them
Once I put all that in place, I started sleeping a lot better. And you know what? Once I had a good night's sleep my anxiety reduced and I felt less like having a drink.
It took a while to make the changes but none of them are difficult things to do,.
