Everything you've written on here is the exact same situation I am currently going through.
My Mum was an alcoholic
And I find myself having a glass (no more than two) every other night
I've sat down myself and really feared it becoming a potential problem
However with my situation
I can definitely go without alcohol
And the cravings can come and go
It all just depends on the situation
If Im feeling quite stressed
Maybe I fancy a glass
If I've had a hectic day
It's nice to have a glass
If I'm not stressed or there aren't any particular problems or events happening
I find myself not even thinking about alcohol or reaching for a glass
As long as you know your limits
And if you ever think it's becoming a problem, either cut down, stop completely or reach out for help
Everyone will have their opinions
But no one's living your life
You know you better than anyone else
The fear is there because of genetics
Completely understandable
We all have our ways of coping and winding down (some more healthier than others)
Some people will smoke 5 fags
Some people will go on a 5K run
And some people like us would like to have a glass or two
There's no harm in that
