Morning.
luci - I hope that you can not drink today but please don't put pressure on yourself. Take it an hour at a time, less if need be.
Jeep busy and keep posting if you wobble. We have ALL been where you are, some more than once, twice or more. We ALL know how you feel. 
WRT DP/DHs not believing that we have a drink problem, don't understand what all the fuss is about, wonder why we are making a big deal about it etc........
The reason for a reaction like that is usually because they don't want their own drinking habits brought into the spot light.
If they added up their units too, counted the empties in the recycling box, you can bet your life that they would be higher than they should be and if they looked at their own drinking habits, for what they are, you can be sure that they too would been seen to 'have a drink problem'
So, like I have, you just have to get on with it yourself. No point in trying to educate your DP/DH for the time being. Focus on your drinking and your habits.
And who knows, in time, you not drinking or reduced drinking may just be the gentle kick up the backside that DP/DH needs to address their own drinking habits.
That is what happened here. I was all 'do you know how many units you had this week?' to DH and 'I think you need to cut down'.....
Mostly because I needed my partner in crime not to drink too. It wasn't fair! Why could he drink and me not?!!
However, you have to be selfish. You have to ignore what those around you are doing and concentrate on yourself. Focus on you. Focus on your goals and who knows, over time, they might see how much nicer it is to be sober of an evening.
My DH has. He no longer drinks in the week and is very controlled at weekends. Funny, once I stopped banging on about it, he did it all on his own! 
Sorry for the long post! 
Hope everyone else is ok this morning.
getting - thank you for your kind words
