Ye it’s a vicious circle being on cocaine. I know people who are up for days on it. I can’t do that.
Coming down off coke makes you depressed and suicidal. Also there a thing called emotional relapse, were he will start arguments with you are blame some one else for things just as an excuse to get coke. Even though he might not be thinking of it, his brain is tricking him to get it. Then it’s mental then physical relapse, where you have picked the coke up. He needs do an action plan to do things to prevent this.
