I almost asked above- are you sober now? So, your plan is to be sober and start seeing someone? That's the best route IMO and in this scenario I would liken therapy to AA - a desire to stop drinking is what you need. So, we don't want you to relapse again, but if you start seeing a therapist now (sober) and are working with someone, as part of your recovery plan, and you relapse, that's different than what I was doing by drinking all along.
That person would be there to help you stop relapsing. It's all up to you of course, every choice to drink or not drink, but I think you know that you're past the idea of using books alone, or the stuff you did when you first joined here.
