Recently (the last six months or so) I've been getting really tired after a couple of drinks (let's say three or four). By eleven at night, I'm ready to call it quits. My friends and boyfriend poke fun at me because I usually head home before they do. How can I last longer in a healthy way? I definitely try to drink water throughout the night, but is there anything else?

What can I say to prevent someone from drunk driving?

Lately, my boyfriend has been sleepwalking. I'll wake up, and he will be sleeping elsewhere — downstairs on the couch, his roommate's room, etc. At first, we thought it was funny. However, now that it has reoccurred (more than once or twice), he is very upset about it. He thinks it is from drinking too much. Could this be the case?

I've heard that drinking coffee and grapefruit juice at around the same time can extend the effects of caffeine. Is this true? I know that grapefruits can increase the bioavailability of some drugs... what about caffeine? Is this at all dangerous?

(1) I have a daughter who just joined AA. She has a drinking problem. What are our responsibilities to her as a husband, father, mother?

(2) Should any alcohol be kept in her house or our house (we are the parents) when she is around?

(3) It has been said that alcoholism runs in families — is this true? Does it seem to skip generations? If so, why?

Do any alcohols have any specific benefits? As in, is tequila better than vodka? And is red wine the best choice because of its antioxidants?

1) I have had acid coming up my throat from my stomach for the last 3 weeks. It comes up and just burns my throat. What is it? Do I have an ulcer? By the way, I get 3 hours of sleep a night, and my roommate doesn't help the situation.

2) I have recently asked you about my would be ulcer. I shall pose the question again. Lately I have this damn acid coming up my throat. I've been under a lot of stress and have strange sleeping habits. I am also drinking a lot of coffee. I drink about 5 cups of coffee a day and my roommate isn't exactly stress relieving. I go to bed about 3:30am and wake up about 5:45am for crew. Am I dying? Do I have an ulcer? What's wrong with me?

My friends take Pepcid AC when they drink to reduce the redness on their faces. Is this safe? I'm worried that it will hurt their stomach linings. Please help.

What are strategies for drinking less in a social situation or for avoiding driving while impaired?

Recently, many of my friends have been doing methamphetamines. Often when they start to come down, want to come down, want to "level" out their high, etc. they take Xanax!!! Now I know Xanax is an anti-anxiety drug, and meth speeds your heart up. So can mixing the two ("reds" with "blues") be especially bad? I keep trying to tell them that it doesn't sound like a good idea...but they know that I hate pills so they DON'T listen. "They know better!" But I haven't been able to find any info specific to my question in other places. CAN YOU HELP?
