Laura -
Probably one of the best things you can do is get your husband on board. Family support, especially a spouse, can be invaluable. You've taken a great first step, and don't worry about your friend's reactions -
I'm not drinking because:
I'm not feeling altogether tonight
I'm on a diet
I'm taking some medication which will react with alcohol
I have an early meeting/appointment/etc.
I'm not drinking
You'll find that the person that thinks about your drinking/not drinking the most is you. Other people will not notice, and if they do, give them an excuse or tell them to mind their own business.
Sneaking vodka was my wakeup call.
Congratulations on the first step, and welcome to the SR family!
