WWG, I'm sorry that you're finding this process difficult.
You say that after 4 days you thought you weren't an alcoholic any more so you could drink again. Those thoughts need to be totally scrapped. I think a good idea would be to prepare yourself NOW for when you get those thoughts in the next few days. Make a list, perhaps, of all the things you are thinking and feeling right now after drinking for four days to remind yourself of what it will feel like if you drink again.
It took me a long time to properly admit that the only option for me was to never drink again. It doesn't have to take a long time. You can make that decision right now.
