Is my vegetarian diet making me feel tired?

I am a vegetarian and frequently feel like it takes a long time to "wake up" in the morning and some days I feel like I never quite get there. I can't help but think this may be diet related. I went to a doctor for a test for anemia which was negative and I always try to get a good nights' sleep (six to eight hours). In the past I have tried to gain weight and failed miserably. I remain a little underweight but get a good deal of exercise each day. Any ideas?


Do whitening toothpastes work?

So far I have been extremely impressed by your service. I trust you with a question which I know many people share: Are whitening toothpastes detrimental to the longevity of one's teeth?


How often should I wash my hair?

The last time I was at the hair cutting salon, the person who washed my hair asked me if I washed my hair everyday. I said I did, and she said she could tell. I'm not sure what she meant by this, but please tell me how she could determine this, and what is the best overall practice for washing hair in terms of frequency. I'm interested in the health of my hair as well as the health of my scalp. Thanks for you help!


How contagious is measles and how is it spread?

A friend of mine is living with someone who might have just got measles (results pending). If true, and my friend has also got it, how contagious is it? I think it is measles, rather than German measles, which I had as a child. Does past illness provide any defense? That is, can you get it twice? I presume having had German measles does not provide any protection against measles.

How is it transmitted? Like a cold? (Physical contact, common contact with hard surfaces, and maybe airborne?)


Is it possible to reopen a closed piercing?

I have two piercings in each earlobe; however I have not worn earrings in the second set of holes for several years. Recently I tried to insert earrings into the seldom-used pierce holes. One earring went in with no problem, but the second did not go through after several attempts (I actually gave up because my last attempt bent the earring post). I have tried inserting other earrings but they also will not go all the way through. Is this something I can fix myself? Do I have to get the same hole professionally re-pierced? Will there be problems with scar tissue at the site?


Should I get the meningitis vaccine?

1) I'm a college student and I've heard in the media that meningitis vaccine shots are recommended. How do I get more information and a shot?

2) As a parent of a college freshman this fall, I was concerned about the increasing publicity that Meningitis has received recently over the networks. Since the population most likely to be infected includes young adults living in close quarters, do you recommend vaccination and where is it available?


Is reusing water bottles safe?

I started buying bottled water because it seemed to taste better. As an experiment, I tried refilling the empty bottles with tap water and refrigerating them. And I discovered that what I really liked was drinking chilled water out of the bottle. If no one else is using the bottles, how often do I need to wash the bottles out with soap as opposed to just re-filling them?
