Are other drinks besides water still hydrating?

I frequently hear that beverages with caffeine or alcohol are not good for replenishing fluids and preventing dehydration. But in reality aren't they just a bit less effective at hydrating your body than other beverages? In other words, if you were stuck in the desert with nothing to drink but beer, coffee and cola, would you actually be worse off and die of thirst sooner if you drank these beverages versus not drinking anything at all?


How to gain weight?

I am a 22-year-old male. I would like your advice as to how to increase my weight. I am extremely thin, and would like to put on weight for both appearance and strength purposes.

I believe that thin people have a very fast metabolic rate. Is there any way of slowing this rate down? Does it fall naturally with age? I have often been told that I should lift weights, but cannot find time on a regular basis to do so. I do, however, have time to do push-ups at home.

Anyway, I'd much appreciate it if you could give me guidelines as to how to increase weight, especially through diet. What kinds of food should I be eating? How many times a day should I eat? How big should the meals be? I hear the soybean is very nutritious — is this true; if so, what could I eat or drink that contains soy?


Is mixing uppers and downers a bad idea?

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?


Am I bulimic, or is it just a phase?

I am a college freshman and I think I'm on my way to becoming bulimic. Since my junior year of high school, I have periodically binged and tried to purge, but I was never really successful and it was never frequent. My senior year I made myself semi-successfully throw up for the first time, but it was gross and scary and made my throat bleed and I stopped. However, since I've gotten to school this year, I feel like things have gotten out of control. I started out eating healthfully and losing weight, because I am about 15 pounds overweight and need to make a lower weight class for my sport. (I am at a high level and compete internationally.) I'm also terrified of the "freshman fifteen" since I've always been chubby at the least. I couldn't keep up my healthy eating and snapped, and now I binge all the time and for the past few weeks have been throwing up. I think I could stop but I'm not sure. Am I bulimic or just going through typical freshman food phase?

Thanks for any advice.


Will past experimentation with drugs lead to permanent brain damage?

I have a history of "experimentation" (infrequent or occasional use of ecstasy, 'shrooms, and other drugs — mostly prescription pills). I am completely sober now, but am worried about long-term damage to my brain. I used drugs infrequently (no more than three to five times for each substance), but drank regularly. How worried should I be? Is there anything I can do to combat long-term effects?
