How does sleep deprivation affect human beings?

Why does being tired and hungry always makes the day seem so looong and boring?

Does the occasional use of cocaine (say once/twice a month) cause impotence during sex soon after one uses it? Would this be a tell-tale sign of cocaine use if the person has no other problems with impotence otherwise? Along with the impotence evidence I see is insomnia and talkative behavior…..

Can Sleep Apnea affect you’r Growth?I found out i have it and haven’t grown in a while can Sleep Apnea be causing that.

cause supposedly i’ve been calling people while i’ve been sleeping. i dont know that im doing it while im sleeping but people have been telling me that i’ve called them in the middle of the night and ask them some weird questions. so i was just wondering if this is a problem other people have.
fyi i don’t drink, or do drugs, or taking sleeping meds

I suffer from sleep paralysis once or twice a month. I’ve read a little bit on the subject and I meet all of the symptoms and all of the causes. I haven’t found anywhere that says whether or not this can be dangerous. Any expert information would be greatly appreciated.
Thanks for the help guys. I didn’t know if this was a topic most normal doctors would know much about. When I go through it I’m conscious of what is going on and so I tell myself to just breath until I regain movement, but the first couple of times it scared the crap out of me.

Im a 15 year old girl, 5′3- 5′4, and i weigh 110 lbs. right now. 2 months ago i weighed 100 lbs. and i had a sleeping heart rate of 26!!!! i was in the hospital a whole month being refed! my heart took forever to recover…
i sorta have an eating disorder… but its really unique. for the past year ive been on virtually a 0 fat diet. i was maintaining my weight… but my heart was still really malnurished from no fat. i had no idea i was hurting myself… so nieve..
then in like 2 weeks i dropped 10 lbs. i came down with strep throat… and then neumonia. i was just starting out at a new boarding school… it was awful.

ANYWAYS, im in eating disorder treatment now. they want me to weigh 130 pounds!!!!! i put on a happy face when im around the therapists so i dont have to stay any longer than i have to, but dont you think thats ridiculous!!! i thought 115 lbs. was a good weight for a 5′3 girl. i havent even had my period yet!

Is there anybody out there whos been through eating disorder treatment or is in it now? anybody have any advice? words of encouragement???

Thanks so much. im just so fustrated with this whole thing:(

I have been getting very little sleep for the past few months. I mean, I get about 2, maybe 3 hours every night. This is due to procrastination from all the homework I get from school. I feel like I’m on drugs sometimes, is that normal?? I’ve been gettin heachaches, which I have never in my life gotten before, and I am hallucinating a lot. I see things in corners and things pass by. I was told that when you don’t get sleep, you’re like this. But, also when people wake me up in the morning, they say I look like I’m on drugs-. Do you think sleep deprivation is linked with drugs? I have never taken illicit drugs, just telling you. I feel like I’m losing my mind!! Such painful tension headaches .. .

I’m hosting an exchange student this year. She’s got a lot of anxiety about school and her relocation and isn’t sleeping She’s asked me to take her to the doctor for medications for this, but as an Ambien user myself I disagree.
We talk openly about the stress on her and do what we can to help. I’d like if somebody could advise me on natural remedies for these problems with diet and vitamins, etc…
Thanks!

for the past year I have encountered the most terrifying dreams, I am awake in my own bed looking down on my body as if I just woke up and I can not move a muscle…My eyelids are so heavy that i want to close my eyes but my panic won’t let me and I know something is there with me and it frightens me and it makes me heavy, It’s keeping me down and I try, I try so hard to move but I can’t It makes me so unimaginably tired to keep trying and i try to scream, but I can’t I just have this shrieking small gasps coming out of my mouth unable for anyone to hear…Im so helpless and I tell myself to wake up…and I can’t…so i close my eyes tight..and I am awake..but I am not awake..I open my eyes and relive the nightmare again…and again…and again…one day It took so long for me to awake, I finally woke up at 5 in the afternoon..I usually wake up at 8 am. I don’t know what this is, I don’t know why this is happening, Im a very happy person with a healthy life. i dont drink, smoke, or do any drugs and anything " traumatic" that has happened in my life has been dealt with…I used to be a catholic..but I have renounced all christian faith…but i don’t belive it has anything to do with " spiritual" stuff…anyone out there who has the same thing happening to them, please tell me I’m not going crazy
