My mother is becoming an alcoholic.

Hi all, I'm 20 years of age and have noticed a worsening drinking problem with my mother.

She has always enjoyed drinking wine over the weekend, definitely two out of three nights of the weekend, but I have noticed an increase in consumption.

The point where it became very clear was a week or so before Christmas. Drinking any day of the week is fairly commonplace in Ireland over the Christmas period but this is the worst thing I'd ever seen from any member of my family. I woke her up on the couch having come in from work, not knowing she had drank, and when I did wake her she looked up at me dazed and confused and drove her head back down into the couch without saying a word. I initially thought she was joking with me but all I could get out of her were grunts and groans. My younger sister and I had to guide her to her room and once by her bedside she dropped to her knees and claimed she couldn't get up. Again, I was none the wiser to the fact that she had alcohol in her system, I actually thought she might have been having a stroke and was the click of a button from ringing an ambulance. When other family members were called into the room we managed to get her into the bed at which point a half litre bottle of vodka hidden behind the couch was brought to my attention. Whether or not she drank half the bottle that night I can't say fot certain, but the fact that never have I ever seen someone so drunk suggests she did.

Nobody has mentioned it since nor has she because I doubt she can remember. Her reasoning for drinking vodka as opposed to wine is due to lower calories and that the addition of mixers tones it down but i can't help but feel that it's a convenient excuse to drink harder.
A couple of days after she kind of opened up on how she has been suffering from depression and that she wanted to turn over a new leaf by doing Dry January and potentially going to AA if necessary. She had pre-booked a night out in early January which she claimed would be the only night she would drink but as I sit and write this late on January 19th she is in the next room with a glass of something, having told me that she finds it to be a release from any issues she is suffering from.
She says that she has toned it down to just the weekends but I still feel something needs to be done to stop her from putting herself at ease through alcohol.

While I think she needs help it is a very controversial topic to bring up and when I've mentioned it in the past it is conceived as disrespectful. I know it's only for the greater good that I'm doing it, but it can still be seen as disrespectful.
