Adipex addiction?

My husband has been taking Adipex for about three months. He’s lost 30lbs and says he wants to take it for one more month to lose 10 more. But he’s been out and not able to go back to his dr for a couple days now. Today he went into a rage telling me he doesn’t wanna be with me or have a baby with me. All because I had to come back and out my swimsuit on when our friends were clearly saving our spot In line at a river. He’s been lashing out making everything my fault when he’s got something going on. Is adipex withdrawal a thing?? Because this is killing me 😢😢 he won’t listen to me but expects me to take the mean comments. My heart hurts so bad.
