Hi Jeff. Two years is such good going, isn't it?
There's a lot of good tips already offered here, i see...but I thought I'd contribute my two cents woeth, and add - that mindfulness truley does help many people ease their stress and anxiety levels. And no need to go through a gp or the mental health services if you dont want to. I notice you're in Portsmouth...maybe you could google when you have time MBSR or MBCT classes? And just have a look...These are Mindfulness Based Stress Reduction or Mindfulness Based Cognitive Therapy programs that run over 8 weeks in a small group. No need really to talk much or socialise with the group if you don't want to... The classes help with a daily practice that really pays benefits. There's lots of research and evidence based info on-line you can read for yourself if you want to.
It would be such a shame to risk going back to using alcohol after you've done so boomin well for something ( your stress and anxiety) that has other solutions. I hope of some help anyway...
