You know what Lucy, my xab doc used to give him anti depressants like smarties, im afraid that some doctors are still very blaze about alcoholism. My x took the "they told me not to stop completley" as a green light to carry on as normal, I didnt beleive it at first but read somewhere that it's really dangerous to stop without medical supervision.
I suppose it makes sense if they are in rehab being watched but left to control it themselves imho spells trouble. Take care
