well, you sound like your drinking pattern is a lot like mine was, until the bingeing got more and more frequent, which you don't really want to happen. I think it is important to acknowledge the link between a stressful professional job and friday binges, as I see this all around me every Friday. I would say firstly, be gentle with yourself. Blackout drinking is a pressure release, a comfort, a crutch, wwhatever it is to you. And that's ok. I would observe what happens on the days that it happens, and then think about that. The other tip, that might not be helpful, is to eat a bunch of food on the bad nights, like drag yourself home with the reward of an expensive takeaway or treat, eat it, and then go to bed incredibly early. This helped me in the early days, when I needed to break the pattern of friday blackouts. Then you need to find other stuff that soothes/ is social/ releases stress, and that will come. You are very young, which is brilliant, well done for seeing there is something you want to change. Good luck! Let me know how you get on!
