I'd say the name of your thread, false sense of security, is exactly right. You are putting yourself in quite a dangerous position. I only say this out of concern because I have done exactly what you are going to without the spiritual defense against the first drink. I failed on every occasion.
Luckily, now I have the tools to be on guard for this. Life has gotten so much better and I can enter a social situation without even having to wonder if my sense of security is false. It isn't.
I wish you well in whatever you choose and hope for the best possible outcome for you.
Let us know how it goes either way!
