Lately, I have been doing a drug called Special K. I know it is a sedative/tranquilizer (what's the difference?), but very little about side effects, etc. Also, can you go over similar information about the drug X?

I have been a smoker for about 8 years and smoke about a pack per day. I am also an alcoholic and now drink about 7 to 10 beers a day, and have been for the past 2.5 years. Last night I decided to quit drinking beer every day and today I am already shaky, nervous, and can't concentrate. I want to quit smoking also so I can join the army. Is it dangerous to quit both at once? Would it be too much stress on my body and mind? And also, would having just one beer a day for the next couple days help with the withdrawal symptoms?

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.

My new job requires me to travel by airplane quite a bit. While flying, I sometimes have a cocktail or two, and most of the time, I am really loopy by the time we land. Some colleagues of mine have told me that one drink in the air is the equivalent of two drinks on the ground. How is this possible?

What is, overall, safer for your body: alcohol or marijuana?

Do different kinds of alcohol (specifically liquor) actually make you different kinds of drunk? Or is it a cultural/psychological thing? I've noticed that I feel different when drinking wine vs. vodka vs. tequila, and I'm wondering if there's a physiological reason.

My 21st birthday is coming up. I've already had two sets of friends and my mom's boyfriend offer to take me to the bar for drinks. The problem is, I have never been drunk before, let alone consumed alcohol. I chose not to drink for a few different reasons and am not sure if I should change anything for my birthday. On the other hand, I feel that I am obliged to go out drinking on this "special occasion."

I am a healthy, fit, 18-year-old male. I have tried both ways: consuming small amounts of alcohol regularly (one standard drink a day) and consuming a lot of alcohol irregularly (10 to 20 standard drinks in one night, but only two days a month, or thereabouts).

I have tended towards drinking a lot irregularly because I have found that I can't notice any effects until I have had at least four or five drinks, 80 to 100 proof shots, usually mixed with soft drink.

I was wondering if either way was less healthy or more of a risk as the same amount of alcohol is ultimately consumed. Also, I noticed that I got a bit more of a 'beer gut' when I had one-a-day than 15 at once; is that likely or just my imagination?

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?
