Most of us can stop cold turkey, but it depends on the amounts you drink and for how long.
If you drink very high amounts every day and for many years I would suggest to see a doctor for advice and assistance.
But you have quit once so I guess you can do that again. It’s difficult to not fall back into old habits like you already noticed. We easily return to drinking when something difficult happends and we have to deal with that emotionally.
What helps is to make some kind of plan. You can read about that here:What's YOUR plan? and you will find mine here:2 years sober and what helped me to get there:. Maybe you see something in it you can use for yourself.
