Hi, firstly I'm glad you are here as that signifies that you realise being functional like I was does not mean there is not an underlying issue needing addressed here, the fact that you have already quit other habits makes you realise that this disease is just as controllable as the others, I'm sure you will draw the conclusion too that we have to stop ourselves before our bodies stop us which will likely happen eventually with continued alcohol abuse.
If you do indeed decide abstaining is best for you please take medical advice as with a large intake on a regular basis medication may be the best course of action to limit any initial symptoms.
On an unrelated note- just a quick congrats too JDooner, 1 year tommorow is awesome.
