Thank you everyone for the replies and I'm glad other people go through this to and can be beat.
On the brain recovery I thought although cells die your brain can improve neural pathways and the like the longer you are sober.
I think the reason I have had these episodes of 2-3 day binge drinking is because I keep wanting to prove everyone wrong that I don't have a weakness. Although clearly I have.
Hope everyone gets through this day and a day closer to the ever ending battle of sobriety
