Question: I never had to worry about STIs before because I went with the same guy for three years, but we broke up in the summer.

Since then I've been with two other men.

Now I'm worried. Should I get tested?

Answer: There is a two-part answer to your question - and both answers are "Yes."

If you and your partners have not been using any protection (such as condoms), the answer is absolutely "YES" -- you should get tested for STIs.

But even if you and your partners have been playing it smart by using protection 100 percent of the time, it is still possible to transmit some types of STIs, such as herpes and Human Papilloma Virus (HPV).

Consequently, you should still get tested for STIs. Confidential testing for STIs is available at University Health Services.

You can schedule an appointment with a clinician in the Women's Health Department or the General Medicine Department.

Question: Does Health Services have a dentist? I don't have time to go back home to my own dentist.

Answer: No. University Health Services does not offer dental services.

However, there are more than 40 dentists practicing in the State College area.

If you want to establish a relationship with a local dentist, you may want to ask fellow students who have used local dentists who they recommend. Or you can check the Yellow Pages.

Question: I am worried that I'm drinking too much coffee. How much is too much?

Answer: The general recommendations regarding caffeine are three cups (or less) of coffee or tea per day.

So, if you drink more than three cups per day, you should gradually reduce the amount of coffee or tea you drink to three cups.

And if you are drinking a lot of soft drinks with caffeine, you need to factor that in also.

Here are some ways you can reduce your caffeine consumption:

Switch to decaffeinated coffee or tea and caffeine-free soft drinks.

Alternate caffeinated drinks with decaffeinated or caffeine-free versions.

When making your own coffee, try mixing caffeinated and decaffeinated grounds together

Limit your consumption of caffeinated drinks each day to a pre-selected number and then switch to decaffeinated beverages.

Another point to remember is that individual reactions to caffeine vary widely.

About 150 mg of caffeine (which would be found in one-half of a cup of brewed, strong coffee) makes some people nervous and jittery, and less than that can sometimes even interfere with their sleep.

But among heavy coffee drinkers, a mug or two will only make them feel pleasantly stimulated and alert, with no sleep disturbance.
