Alcohol and benzo as a combo can be lethal...not trying to scare you. Usually they aren't, but just a heads up.Vicodin in hard core. It all is, if he is mixing them up. It's up to you when you set limits on your son. I did tell my nineteen year old daughter to leave and had to hear her words in my ears for three long weeks when she wouldn't speak to me. "I HATE YOU FOREVER!"
I won't lie and say it didn't kill me. All I did was cry...at home, at work, shopping...I didn't care. My baby (I could still see her adorable baby face) hated me and it was my fault, I thought at t he time. I even thought, "She takes drugs because of me." But I've talked to her about it since and her reasons for using drugs had nothing to do with me. It had more to do with her peers...but that's another thread. I digress.
Tough love resulted in her quitting...finally letting her go and saying she had to make it on her own with no help from us. She found a place to stay and cleaned up, got a job and walked to and from the job, quit even cigarettes (good for this mom because I hate cigarettes) and is now over ten years clean and a good little mother and has a SO of twelve years. And her own house. This can happen for your son. I truly believe. and see it over and over again on this board, that once we truly set them off on their own and quit bailing them out and worrying about if they will like us or feel abandoned, that is when they start doing better. I don't recall ever hearing about a young adult who lives at home and uses, or who is supported from a distance with parental money, get better. They don't have to. And it's hard to quit. You feel very sick. Chances are, if your son acts normal, he is still using. They do not act normal at all when they are needing their drug. I have learned, through extensive reading and watching Intervention (good show) that heroin addicts, for example, can not function until they get their hit of heroin. THAT is when they act "normal." When they have taken a hit. Until then, they are "dope sick" as it is called. They are shaky, weak, sick, vomiting, not good at all. Eventually they need heroin to feel normal...it doesn't even get them as high as it once did, but they need it to ward off the illness. I am thinking most drugs work this way, including alcohol.
Do what you feel comfortable doing, when you are ready. I feel, and I could be wrong, that the more you set boundaries and refuse to enable the better they do in the long run. It may take a few years on their figuring life out on the streets without our money, but especially right now quite a few of the difficult children on this forum are doing A LOT better. But none of them live at home or get our money anymore.
Hugs and try to find peace today. You can't control yourself, but you can control your own happiness. You deserve it!
