Are there preservatives in saline solution safe?

As an avid contact wearer, I use saline solution to rinse my contacts daily before each use. Recently, a friend told me that many commercial saline solutions contain preservatives, which could affect the overall health of my eye. Is this something I should be concerned about? The saline I use has always felt comfortable so I never thought it could pose a problem.


Which type of contact lenses are better?

I read that disposable contact lenses are actually worse for your eyes than the normal one-year ones because they allow less oxygen to go to your eyes, and the only advantage is that there are less cleansing problems. Also, it is claimed that inadequate oxygen to your eyes (possibly caused by prolonged wearing of contact lenses) leads to a condition when extra blood vessels sprout around the iris, which leads to sight problems at old age. Is that true?

I am very concerned because I normally wear (one-year) contact lenses from 8am to 8pm, and maybe to 12am during reading periods. I don't feel very comfortable with glasses because they give distorted visions and fatigue. I thought switching to disposable contact lenses would do my eyes good. My current lenses contain 38 percent water. Is this good enough?


What are the long-term effects of tripping on cough medicine?

1) What are the long-term and short-term effects of abusing NyQuil? I've heard it's very dangerous to use it recreationally, but I'm not sure what's dangerous about it. I've heard you can even die from abusing it.

2) I have recently just finished my first year in college and on a few occasions, a couple of friends and I had decided to drink massive amounts of Robitussin DM (dextromethorphan, I believe). It was fun, but the day after I felt like I was hit by a car! They call it robo trippin'. I have no intentions on doing this again; however, I was wondering if there were any long-term effects of it.


What are the health effects of recreational codeine use?

I like to use codeine occaisionally (once or twice a week at most) to help me relax and feel a minor high. Typically, I'll take about 90 to 150mg per session (100 to 200mg per week on average). Sometimes I take Tylenol-3's, and sometimes I extract the codeine from these pills and drink it pure. What are the potential health side-effects of this usage, both short- and long-term?

Thanks!


How can I prevent athletic performance anxiety?

I compete in an individual sport. The problem is that on the day of a major competition, I have really bad indigestion. Sometimes, I have to run to the bathroom every half hour for a bowel movement! Besides being annoying, disgusting, and a little embarrassing, this interrupts my competition and adds unneeded stress. Why is this happening and what can I do to prevent it?


Is it dangerous to hold in number two?

My boyfriend and I have been together for almost three years, and we've lived together for more than one, but I still can't do Number Two when he's in the house. It's not a problem during the week when we both go to our separate jobs, but on the weekends, it's usually just the two of us in the house all day (and night) Saturday and Sunday and if I feel the need to poo, I have to wait until Monday. My question is this — are there any adverse health issues I should be concerned about with waiting to poo? I know that holding your pee can give you bladder infections, but is there a similar issue with Number Two?
