I am glad you are back and ready to try again. But let's not kid ourselves, relapse is a serious thing and there is no gurantee that any of us will get another shot at sobriety. Not everyone makes it back, probably much to the horror of those that went out and found they could not get back.
My suggestion is to review what you have been doing so far and find out what needs to be changed.
If you have been honestly following a recovery program, taking all the suggested actions etc, and you end up drunk, maybe you need a different program.
If you haven't been giving it your all, perhaps you can work out where you have been holding back and identify exactly where it went wrong. In AA we might look for a secret kept, and amends we refuse to make, or maybe we dont help others, or perhaps we don't do the steps at all. Who knows? You do. No one else.
