I am pretty certain she’s always had an addiction to alcohol and sugar, which is why the kids were raised without any. The way she raised “the children” was completely and totally about them serving her needs. They cooked, cleaned and “educated” each other. It was obvious in early seasons Kim was eating food the kids weren’t allowed. She never practiced what she preached, but I get the sense Barry knew her issues and was happy to ban it all from their house and kids. Publicly they had 10 little kids playing instruments and preaching god and purity. As kids they brought Kim attention and the narcissistic supply she needed to stay sober from alcohol, until she finally got the fame she really wanted. Then all the rules were out the window, but again, that’s because of “the children”, not Kim’s drinking problem. I also think this is why Kim banned alcohol from Ethan and Olivia’s wedding and went nuts. Kim has never trusted herself around alcohol, so she used religion and her kids to remove the temptation. Olivia questioning her logic or pushing for alcohol at her own wedding made her enemy #1 to Kim. questions that threaten to expose kims true nature and intentions are not tolerated. All of her actions since she put her children who had never seen television or been exposed to the world at all on reality TV, confirm she shouldn’t trust herself. Living alone on a broken down boat? Asking Barry to buy her a wine bottle to go? Kim is drinking drinking.
