DH has been taking Sertraline for about a month and I estimate is drinking 35 units of alcohol a week, should I be worried? I have spoken to him about it and he became very defensive, said doc says he should do whatever takes to relax. He is also trying to hide the drinking so it is difficult for me to be sure how much he is drinking. The Sertraline is to help him sleep as he is very stressed in a new job.
