I did detox over here in Germany a couple of weeks ago. I did not have any physical withdrawal signs, so they did not give me any meds at all.
The day arrived they took a lot of blood samples and checked them. The first three days they also came regulary (morning, noon, evening) to check my blood pressure and body temperature.
They also had regular group sessions that had to be attended in the evening. Spokespersons from support groups came in every evening to introduce their group / program.
I thought like you that it would be really hard to stay sober in a hospital, not being in your own comfort zone etc. However, for me it really wasn't. Once I was there... I did not even like drinking at all. Alcohol was so far away from me... I think it's a good start your quit!
