Hi,
Be sure to read Carol sticky found in the Alcoholism section on quitting, great information here.

As far as fluids you need tons of them when you stop drinking, gatorade with electrolytes is a good choice unless you are sugar sensitive. Doctor care during WD is highly recommended!
They crankiness and not feeling so well is very normal for a few days but it does pass. Then the peace you can start to feel without having a poison in your system is fantastic. I never realized how much alcohol taxed my system.
Take care!!
