Hi, Littlesoul:
I don't want to reiterate what others have already advised, so I'll just share my experience. I am newly sober (21 days) after a relapse, and I have finally (I hope) surrendered. This time I wasn't drinking daily or to excess, but the first time I got sober (4+ years ago), I was a heavy, daily wine drinker; and I HAD to go to medical, in-patient detox. I was drinking so much and so steadily that I knew I was a high-risk candidate for seizures (which can kill). It was the best, most well-advised decision for me, and it gave me the physical foundation upon which my mental foundation could take root.
Stay well, and try to avoid the grocery store at all costs! If you're feeling physically ill, please seek medical advice/supervision (e.g., the ER). Take care of yourself.
You have your whole life ahead of you, please know that.
