It took awhile for the alcohol to get out of my body. It's truly IN us from head to toe, skin, pores....I had horrible night sweats for awhile and it was some weeks before the lessened and went away, as the nightmares eased to dreams then to decent sleep. I'm a pretty extreme case.
I also got all medical tests and stuff like my thyroid back on track once the alcohol was out of my body. Hydration and so on, and good dr care, and most importantly - staying sober...it all gets better. Keep going.
