To be honest, now I don't drink I don't get the same mood swings.
I also seem to be able to 'laugh' myself out of a bad mood too.
I've developed coping mechanisms to sort of laugh at myself when I am grumpy. I think to myself really, is this such a huge big deal. Then I start smiling.
I also find ringing someone else helps too.
I think the lack of bad moods is also because life is a lot more stable now. Not as many bad things happen.
I created a lot of my own trouble by drinking.
The early days were hard, but now its second nature.
My best to you
