Why do people think GPs have magic wands when really they are marketed to by drug companies and give out whatever drug companies tell them to at that time? Right now it's SSRIs.
Here's one for you. Start getting up very early, like 5am. This way you will be so ready for bed and so tired by 10pm that you won't have time to drink. You have to create this habit. My anxiety goes through the roof sometimes and if I'm more tired (but functional) I just don't have the energy to snap or obsess. I've been waking at 5, well doesn't go to plan some days, but it's the thing that's going to stop me seeking out destructive behaviours in the small hours.
It's habits that will change your situation. Drugs can help in the short-term and usually SSRIs aren't short-term, there's never an exit strategy because unfortunately the pharmaceutical industry and medical establishment are compromised by profit.
Habits are your friend, and you can't expect to create the habits at the very time you would indulge in the harmful habits, that won't work. What you need to do is create a habit pre-emptively, such as getting up very early, for instance, that will start working at the very time you would do the bad habit.
Alternatively and to accompany this try a gym or workout session, even a walk, make time for this. If you have kids, it's the park for an hour after school. Anything that will render you less inclined to drink later on.
Now, I'm assuming you drink in the evening but if you drink in the day that's a whole other issue. But I'm happy to speak to you around that also. I'm not a therapist, just a person whose been through a lot making an effort to live a functional life.
