I have recurring insomnia which lasts for about eight to twelve days. It seems to begin at about the same time each month. What are the common causes of sleep disturbance? Any suggestions?

My entire life I have always talked in my sleep. According to my parents, it is just something I do. Both my parents say that it is almost impossible to sleep with me because I'm constantly kicking people, screaming, moaning, grunting, or anything else active in my sleep.

It's never been a problem for me, because I never remember doing any of it, unless I wake myself up while screaming. But now that I'm living with my fiancé it has become a problem. He's a lite sleeper and well... I'm not. So when I'm moving around I wake him up, and he never gets a full night's sleep. He's even occassionaly taken to sleeping on the couch. So I was wondering if there was any methods medically or herbal which might be able to stop my over-active sleeping patterns.

1) Are wet dreams in a sexually active 23-year-old male unusual?

2) I only had about three to four "wet dreams" in my entire life and now I'm 20 years old. I wonder if it is normal, or it's because I masturbate often that I don't have these kinds of dreams. Is there a way of having one like that again?

3) I have a normal sex life with my wife (once or twice a week), but I have been having a problem lately. I have had about four wet dreams last year. I don't know why but I feel really bad about this. Is there something wrong with me? How can I stop this???

Is there any way that I can reduce the amount of sleep I need voluntarily? Right now, I need a lot of sleep (ten hours or more) and I would like to reduce this so that I can sleep healthily for eight hours a night. Is this possible, given the way that my body works? I have heard that it is, that I can "train" my body to require less sleep. It certainly isn't healthy to sleep fewer than eight hours if my body needs ten, of course. And I'm sure that some people are forced to sleep for six or fewer hours a night for years! Do their bodies just adapt?

Some roommates of mine and I have been thinking about sleeping lately.

Usually we're all told to get eight to nine hours of sleep, and a lot of the time we do! The problem is, once in a while, when there's an essay to write or exam to study for, I or my friends may end up having no choice but to be up until 6 in the morning. No one's really explained what the best thing is to do if you have to be up.

What would you suggest? Should we eat? Take a quick nap before class, sleep during the afternoon or wait until evening? Any suggestions you have would be great.

1) I often have a bad taste in my mouth, and bad breath as well, I assume. This doesn't stem from poor hygiene: I brush my teeth at least three times a day, and usually more. I'm wondering if there is anything I can do about this. Could this be a symptom of some sort of nutritional deficiency? I think my diet is pretty bad, although I'm working pretty hard on getting more protein and eating less fat. I've also been nauseous a lot lately, and vomiting some. Could that be related?

2) Like many people, I often have an embarrassing bad breath. Listerine and other mouthwashes won't be of any help for this chronic problem. There are lots of products available to get rid of "volatile sulfur compounds (VSC)" - that supposedly cause this — and I just don't know which one I should try. Also, what's your opinion on tongue-brushing?
