As biminiblue says, if you dou want to quit by all means jump in - you don't have to be on the wagon, you only have to want to be.
Personal hygiene and household chores were one of the casualties of my drinking too.
In a not quite related sentence, on my Tube journey (underground railway) this evening there was nasty "trod in" smell. Once I got out of the station I checked my shoes and was relieved it wasn't me. Most unpleasant though.
There is a middle aged drunk man near where I live who habitually walks out between the traffic on a very busy road. I am amazed he hasn't been run over. I think the only thing that saves him is the fact that the traffic is barely moving which also means there is no escaping him if you are in a car. Very sad.
