I hear ya buddy.
Stop second guessing yourself and stop putting alcohol in your mouth, at that point you'll be sober. No one can "fool" you into drinking alcohol unless someone legitimately spikes your drink. Don't believe you don't have the strength so simply abstain from alcohol. Stay away from it for a couple weeks and the withdraws should subside, at that point it starts getting easy, 30 days, 60 days, 90 days and by then you're living happily without alcohol and the cravings & thoughts for it will surely subside. At that point it's just about self control and accepting that you cannot drink alcohol because you cannot just have a few.
I would say good luck but you don't need luck, you need will power and we're here to support you through this.
