I'm sorry your plate is so full. It sounds to me like you need to get into a treatment center so that they can keep an eye on you for a while. What bothers me is your elevated heart rate. Having elevated heart rate while trying to come off of alcohol is not a good symptom. It can be fatal. Forget about trying to do it on your own.
I'm really sorry that your husband is not being more supportive. You have some issues going on but it sounds to me like he has no interest whatsoever in supporting you. When one spouse is having problems with alcohol and or drugs and the other spouse has intentions of going out and going to a party so to speak, that's a pretty good sign that they have a problem too.
If your husband has a drinking problem, it sounds like he's not going to be willing to give up the alcohol that's in the house and that's not really good news for you if you are as alcoholic as I am.
I would really encourage you to find a way to get to some AA meetings, find yourself a sponsor and start getting into the steps. The sooner you start taking the 12 Steps the sooner you are going to experience real recovery. You're going to need God strength in order to stay sober in a wet environment and take care of kids at the same time.
You should also start getting with some women in the program and start getting some phone numbers and use them. Also, if your husband doesn't want to stop drinking and support you I would not put any expectations on him because that will only make matters worse.
One more thing. When you come to the crossroads and are thinking about drinking, you have to learn to play the scene all the way through. It may feel good for a short of time but what's going to happen afterward. When you wake up oh, are you really going to be any better off than you are right now? Unlikely.
You can make yourself a concoction of honey and orange juice to drink and help combat the cravings. Anything with sugar because alcohol has a lot of sugar.
You need some sober friends now more than ever and I don't just mean this app.
