Sobriety

My lovely lady suggested that i get sober, we have a baby on the way as well due august. So me and her had an argument a few nights ago while i was drinking, she wouldnt leave me alone so i could chill out so i took off in one of our cars, i ended up with a dwi because the headlights have a short so when i hit a bump they go off, she bailed me out today, and i am really grateful for it because it has made me realize that i need to get sober as much as she wants me to get sober. Its really hard after 6 years of being a hard core alcoholic. So here i am day 3/ or 4 of it and i cant seem to get any sleep, the cold shakes suck and its really getting to me! The only thing my mind is saying is to go get a drink but i want to be better for her and for me, so please if you can spead your support for me because as a person trying to get sober this isnt as easy as i thought. I thought itd be a breeze because i gave up my drug addiction, but now i realize i never really gave it up i just replaced it. Thanks in advance will keep you updated
