I believe your coisun could have it. But i wouldnt say he is a dirty person for getting it. I think he should have used condoms!!! And the girl or guy he did it with was dirty. But people make mistakes. Some people you trust with your life and then you do it unprotected with them and then you find out you have an STD. And there is nothing wrong with having sex before marriage. 96% maybe more of people have sex before marriage. All i say is use protection.

Recently, I was doing well when my doctor started me on a dose of 500mg Valtrex. However, when I began taking twice that amount, or 1000 mg, I started having some killer hot flashes, mood changes, like irritability, and headaches pretty much immediately. But, I'm feeling better, and the side effects are down. The physical complaints and side effects I'd had earlier decreased. So, all in all, it seems like it was well worth it, to go with this medication.

Here are some pointers for those who have insurance and take Valtrex. My monthly co-pay for this prescription is the same whether I am prescribed 10 pills or 30 pills and the prescription has refills for every month. Even though I only take 500 mg a day, I had my doctor write the prescription for the 1000 mg dose. That way I can cut them in half, thus cutting my cost in half. If you only need to take the Valtrex as needed, you can save a considerable amount of money with this plan. The pills aren’t going to “go bad” so you can save them for when you do need them.
