Welcome and congratulations!! It is indeed frustrating when loved ones don't understand the struggle. I would tell my wife about my problems with alcohol and tell her I planned to quit. She would agree but then later that day when I started to get irritable, she would suggest I get some beer!! Ack!! Geez, no! It's hard enough when I am fighting my own brain.
Day 4 is awesome and it is my understanding that is when the last of the alcohol has left the system. I am only on day 7, so I cannot speak on the easier part...yet, but that is what I have heard.
