It's been about 3 years since I had a drink, I was never a big drinker in my younger years but for a number of reasons it started to escalate at about 30 slowly climbing.
As a bad depressive episode started to set in it got worse and within a few years I was drinking a bottle of whiskey a day everyday and had a benzo addiction just to add to the mess I was in.
It took a bit of work with assistance from drug councillors and at least I didn't need to take any benzos for the withdrawal as I tapered off them at the same time, it took a couple of goes but I made it in the end.
I'm very much a all or nothing type and know I can't drink at all, it keep it clear in my mind without confusing options, IME it is a very bad substance to abuse if you have mental health issues, it certainly made my depression worse and was damaging my body, I had an interal bleed at one stage.
It has proven relatively easy to cut it out of my life, my partner still drinks and has a glass of wine in the evening and it doesn't bother me at all, neither does going out with others that drink, if asked why I don't drink I just tell people I have had a problem with it in the past, they are usually just glad of a lift home.
Others may be able to reintroduce it in a social and non damaging manner, but my first question to them is are you sure you are not just finding reasons as to why you can start drinking again.
