My husband received a prescription for hydrocodone a week ago. Well I just checked and he only has one left there is also a bottle of tequila that I'm pretty sure he drank as well. I believe he had become dependent on alcohol and he's in denial. I'm 6 months pregnant and don't know what to do. He's in the military so I don't want to do anything that will jeopardize his career but I also don't care about that because of the harm he's doing to himself. Should I reach out to his family first or what ? Please help
