Normally, 3 drugs are given for HIV prevention, and they are pretty powerful, high dosage medications. The first couple of weeks of treatment with HIV meds are pretty tough, with common side effects including diarrhea, nausea, dizziness, loss of appetite, rash, and abnormal dreams. This will normally go away after 2-3 weeks as your body gets used to the meds.

Most researchers aren't really worried about "Superaids." Most of the cases of "superaids" reported in the media were the result of an individual having sex with multiple hiv-positive partners in a short time span and being infected with several strains of HIV at once, which meant resistance to available medications and much quicker disease progression.

So stay away from male-on-male orgies, and you should be okay.
