I remember those 3am wake ups, mostly because that's when the alcohol was probably just leaving my system finally for the night. You can do this if you really want to, but you must want to do it for yourself first and foremost.
Honesty with yourself is one of the cornerstones of getting sober. I know for me there was also no possible way I could have gotten sober without the support of my family, so I'm not so sure how successful you will be if you try keeping it a secret from your husband. And in all reality, if you keep drinking you'll probably eventually lose your marriage and kids anyway, drinking usually takes away everything in the end.
