Hi Angel, you're doing really well, so give yourself a pat on the back. I certainly wasn't secure by your stage; most of us aren't. After preparation, why not arrange for your husband to leave some money around? You can resist, and your confidence will grow.
Do you have a plan to keep yourself on track? Activities, support group, relaxation exercises? It sounds like you might be concentrating on the negative of NOT drinking, rather than building a positive about being sober, clear headed and proud of yourself. Sobriety rocks; you can relax, stop worrying and have your family happy.
