Sorry for your struggles. Anybody who is sober had to go through the same cravings. They may drive us crazy, but unless you are physically dependent, they are just thoughts. Thoughts can't make you drink. Only you can make yourself drink by picking up.
I don't advise putting quitting off until the 5th. It isn't going to get any easier, and the resolve you have this very moment may fade. Quit today. Right now.
Perhaps it is time to tell your husband about your problem. Support is important. And get rid of all the alcohol in your house. You can only give into your cravings if there is something to drink. With an alcohol-free home, you can't drink.
