WOW injecting oranges with Vodka, amazing. My ABF would go in the basement and drink. I would say, are you drinking down there, Nope, he would respond. But the amazing thing about heat vents, you can hear the top pop on a can. He would be 'sober' for a few months at a time, so I thought, until his Dad said, he is hiding it from you don't believe him. He would always say I had my work cut out for me if I was going to stay in that relationship, wasn't that the truth and then some. The truth comes out in the 'end' but getting to the end is the hardest part.
Good luck, welcome to SR (it keeps me sane), and keep coming back.
