Will Valtrex protect me from developing genital herpes from a partner who has a cold sore?

Dear Alice, 

I take Valtrex daily to protect me from cold sores I get on my face. I haven’t had one since I started taking it a few years ago. My partner gets cold sores on his mouth and has recently performed oral sex on me while having a cold sore. Will the daily Valtrex protect me from developing genital herpes? How will this affect me in the future?


What can I do to stop spending time online?

I became quite the hermit after high school graduation, and noticed myself being a terrible internet junkie who spends hours online.

I realized this was making me feel really irritable after about a year of it, so I started visiting old and new friends last week, and plan to do so this week as well. I'm trying to limit myself on the internet to one hour a day or avoiding it completely.

I'm a young fellah, very able bodied, and I know this. I want to know more of what's out there. I need ideas of how to keep myself moving and build up enough momentum to get out of the small rut. You only live once, right?


Why am I insatiably hungry and losing weight?

I've read a lot lately about midnight snacking and late night eating and obesity and calorie worries, but my problem lies in the opposite direction — I'm LOSING weight, and insatiably hungry, day and night! The only advice I get is, "Eat healthy," which is preaching to the choir, since I consume more fresh produce, mostly vegetables, and home-cook all my own meals. At a recent nutrition check-up, the nutritionist patted me on the back in congratulations for having one of the healthiest lifestyles he's seen, and shrugged at my inexplicable hunger. The fact is, I'm in the kitchen every other hour, and my body doesn't differentiate between awake and asleep anymore when it comes to hunger. I go to bed on a full stomach, and wake up every three hours to eat again. It's exhausting! I'm falling asleep during the day — but never more than an hour, because hunger strikes. And amid all this, my grocery bill climbs and my weight drops. I don't get it. What am I doing wrong?


Am I too nuts for nuts?

I just checked serving sizes for different kinds of nuts, and it turns out that I eat 500 to 1,500 calories worth of nuts every day. I eat a couple of different types (almonds, peanuts, cashews) and nut butters. I've never had a problem with this; I'm on the thinner size of average and feel relatively healthy. I know nuts are healthy for you, but can they be too much of a good thing?


How can I get rid of pubic lice?

1) I have recently discovered that I have what appear to be crabs in my pubic hair. They are itchy and annoying and appear to be laying eggs. How do I get rid of them?

2) I think I have pubic lice, a.k.a. "crabs." Do I need to see a doctor about this problem, or is there over-the-counter medication of some kind I can use to expel the little buggers from their new home? Also, I'm curious as to how I got them since I haven't had sex for several months and this is a recent development. Can one contract this problem from sharing clothing, towels, or bedclothes?


Can being hospitalized for anorexia be helpful for recovery?

I am a freshman in college and I also happen to be anorexic. I have been to the medical services on campus and I am going to be attending the eating disorders group at my university. I also have been seeing an individual therapist for three years, but my weight is pretty bad right now. The doctor who has been keeping tabs on me says that I am very close to my “critical weight.” My therapist and I have discussed hospitalization ad-nauseam, but he's really not in favor of it, saying that hardly anything can be accomplished in a one month stay (which is basically all insurance companies allow for nowadays). He also said that the whole system is like a “revolving door” because people typically go back to their “old” behaviors one to two days after their discharge. However, I feel like the hospital might be the best place for me right now. My parents also are kind-of against the hospital. I really don't know what to do because my gut feelings so contradict my parents and partially my therapist. Also, what is the relapse rate of anorexics after they are released from the hospital? Is there any info on that?


Are waxy fruits safe to eat?

I get the apples provided in the dining hall on campus every day and have noticed that they are completely coated with wax (scratching the surface produces white flakes). I was wondering, how harmful is the wax if I eat two or three apples a day?


How long does it take for HIV antibodies and symptoms to develop after exposure?

My question is about AIDS/HIV: I had a sexual affair that lasted two-and-a-half months, and, unfortunately, I was not using condoms. I happen to know nothing about my partner's previous sex life. I know that, for a test to show something, you must wait for six to nine months. I would like to know whether, provided that I am infected, I will experience any symptoms in this six to nine month period? Is it possible to have the virus and not have any symptoms or indications all this time? Right now, I am a graduate student and I am experiencing anxiety, fatigue, sleepiness, weight loss (three to five pounds in the last two months). Are these related to the disease, or is it just in my mind?
