Post the URL where Dr. Bob stated that.
JESUS CHRIST, how many times do we have to tell you that you did not have a risk! Consider your stats. If you went to a hospital asking for PEP, they would have told you to go away. Remember, as Dr. H says that saliva seems to inactivate the HIV virus. Theres maybe a one in several billion shot that you are HIV positive, meaning that your odds of getting killed by a bumblebee stinging you in the neck while circus elephants tap dance around you are better. Relax. No risk. Get tested if it will relieve your anxiety but don't worry at all. Now, I certainly suggest talking to a healthcare provider about Xanax and other anti-anxiety meds. You have a serious health problem, but HIV isn't it.
All of Asia will be dead tomorrow, all highschool students will die too.... make that Jr High.
Put it this way, I would trade you risk levels in a heart beat.
