1) My problem is this: whenever I have to study late at night, or do anything late at night, I usually have trouble (a lot of trouble) concentrating on whatever it is that I have to do. I'm not going to try anything like No-Doz, but when I drink coffee or anything with caffeine, it just knocks me out even faster. I can't believe it — it's like caffeine's some kind of sleeping potion for me. Some of my friends say eating while you work can help you stay up. I tried that, too. Didn't work. Any suggestions? Or am I just better off sleeping and leaving the work 'till the next day?

2) I am a junior in college. I am pre-med which means I study all the time. However, I can really only focus when I study at night. When I study during the day, it seems that I cannot recall as much information as opposed to studying late at night. How come I can't stay focused during the day? What should I do to help me concentrate during the day?

I was wondering if people can die from not going pee. How long can a person go without peeing and, if they cross that line, then what will happen? Also, can you get a blood infection from ignoring a bladder infection?

I find that I'm most alert late at night, and at school I'll stay up till three or four in the morning. Since I've had morning classes in the past, I've tried to form a habit of going to bed earlier — around midnight or one — but realistically, I don't think this is ever going to happen. I was thinking of trying, when I go back to school this fall, to go to bed around three or four and sleep for four hours, and then also take a four-hour nap during the day. Is this a good solution, or will I be more tired than if I sleep eight hours straight at night? Thanks!

I'm a 21 year old woman with white lumpy vaginal discharge (odorless)...I thought it was thrush but after two courses of yeast infection cream it has not resolved...I have never had sex, so can't have an STD...I get bad pain in my lower back and sacro-iliac region with my period and with ovulation though I don't know if this is relevant...I'm embarrassed to see a health care professional about this and don't know if I'm just concerned over nothing...

Do you have any suggestions for trying to stay healthy and sane while working the graveyard shift?

Thanks very much.

1) When you are at the gym exercising do you need to wipe down each machine that you use even if you are not sweating?

2) I'm looking for some helpful pointers you might have on the subject of health club etiquette (i.e., don't wear perfume because others will leave workout equipment wearing your perfume). I would appreciate anything you have to offer on the subject.

I would like to be able to cuddle up to my partner at night, but I can't sleep if anyone is touching me even a little bit. I'm very prone to insomnia as it is, so it's hard to practice. Is there a way I can learn to sleep differently?

I have the biggest problem getting out of bed in the morning. I set two alarms and I still go right back to sleep. For this reason, I am always running late to work. Do you have any suggestions on how I can make myself get up earlier in the mornings?

Thanks in advance for your help!

I am a 19-year-old male. Over the past three years whenever I urinate, my urine stream splits in two (one continuous stream and one stream which is basically drops of urine.) Is there something wrong??? I also have another question. My grandfather has prostate cancer. I was just wondering when I should begin checks for this type of cancer.
