Stewy I have been hoping you would come back and give this a really good go again. Just focus today on getting your head on that pillow tonight. If you feel a vicious craving go straight home and have a nice long hot shower, maybe another snack and a soothing herbal tea or just a glass of water.
Then you can get to bed and be safe. Yes cry if you need to. Nothing matters apart from staying sober today. Nothing.
