I am an ex-hardcore drug user — speed and cocaine to heroin — with 25 months of sobriety from drugs and alcohol. Now that I do not go out to clubs or party, I am finding difficulty in relationships.

Women do not understand why I do not drink. When they ask, I tell them where drugs and alcohol have gotten me in the past. This always seems to scare them off.

I feel guilty not telling them that I used to be an intravenous drug user, but when they ask about the tattoo on my arm that symbolizes a promise to myself never to inject again. I am honest about what it stands for. I never shared needles, I have been tested for AIDS/Hep-C and all of the tests have returned negative.

I am having difficulty finding someone that understands.

I have been taking between 5 and 10 mgs of methadone daily. I cannot seem to stop. Every time I try, I get very, very depressed and experience abdominal pain, chills, hot flashes, and sleeplessness. The depression and tremendous anxiety are intolerable and I end up taking more to avoid it. Question: Am I harming my body and/or mind with this stuff? How can I get off without the horrible feelings?

I have just realized that I am not able to handle alcohol. Whenever I go to a bar or a club, I drink to excess. I do not have any urge to drink. However, when I am in a club or a bar, the same thing happens: I drink too much! This is making me think that I am an alcoholic. My question is: Where can I go for help? Thanks.

I want to thank you and Columbia for this wonderful service! I have been browsing your archives for some help, here is the situation: I want to know what I can do to support my significant other when he is released from Drug Rehabilitation. Please help me!

1) I found a white powder in my friend's car and I think it might be cocaine. I'm not sure if it is or not. I don't know if I should confront him with it or what I should do. I don't want to see my friend get hurt, but if I'm wrong, I don't want to falsely accuse him of something like this. How should I go about handling the situation?

2) I am a first-year business student and have a little sister who is a junior. I think she is doing cocaine because I found some "paraphernalia" in her room last week. What can I do without damaging my relationship with her?

What can I say to prevent someone from drunk driving?
