My drinking was at least on one level an attempt to eradicate stress.
I've realised in my sobriety it's not possible to do that - or desirable.
I find somethings very helpful with stress - exercise is good, diet helps, deep breathing does too - I've had to work hard to find healthy ways to relax.
I've worked hard on my boundaries to try and achieve that - I think a lot about balance in my life and about what part of the world is mine to operate in - I have to be wary I'm not trying to solve problems that aren't mine, or taking on responsibilities that are someone else's.
I found counselling useful, so I second nandm's suggestion - if you're not doing it already, it's worth considering I think, Tendencies
