Do or do not. There is no try. Yoda
Hello Paul, and welcome. Are you ready to accept help? What if that help is founded on you not drinking at all and being abstinent from drugs?
Your own willpower is failing to control your drinking and you are worried about your drug use. I’ll ask you what they asked me when i came into AA to get sober “Are you done yet?”. Are you ready to let go your self powered control, accept help and do what is suggested to you even when you don’t want to do it?
Check out the many ways to get and stay sober listed on this discussion. Blessings on your house 
as you begin your journey.
