Hey, you have to be patient. Speak to him when he’s sober. More people than not will never quit. If he’s having it here and there it’s not an issue. I used to be the same but if you carry on then here and there turns out to be all the time. Try mindfulness or if he is religious try praying. I’ve found through my research that people who are addicted are not happy with something on their lives. I used to be shy and it gave me confidence. We as humans are made to connect with other people we are social when we can’t sussfully connect with other People we connect with drugs. The more you argue with him or threaten to leave him it will have the opposite effect. No one stops until they really want to. Support him love him. It’s hard. Also look in the net for something called gabba and natural foods to increase dopamine in the brain. It is a life long battle ! Have to fight it everyday. I am trying and that’s why I joined this forum talking really helps try the charity mind and counclling !
