I have just gone through home detox with my sister for her alcohol abuse. We have just gone a day over the detox and I have found out she has been secretly drinking for the last two days of the detox..she snuck out while I was asleep and bought the drinks. I have found a total of 8bottles in the house including receipts however she is still looking at me and swearing she has not drank had anything to drink and how dare I make those assumption. We are the only two people in this house yet, she is sticking to her gun and claiming her detox was fine. I don’t know what to do any more. I feel like giving up but she is the only family I have and I don’t know how to let go
