All the above advice is absolutely valid.
PEP varies depending on the doctor and the patient. But it usually involves a combination that includes Sustiva and Ritonavir (occasionally in the dual-Protease Inhibitor format of Kaletra).
As grueling as PEP is (and it is), it should be remembered that PEP is actually just like going on anti-retrovirals for someone whose 'time has come" to begin treatment. As such, I am something of an expert, having been on six different "cocktails" in as many years.
Expect the usual assortment of gruesome, debilitating side-effects: uncontrollable, "garden-hose" diarrhea, pain and/or numbness in your extremities, the typical nightmares and sleep terrors for which Sustiva is notorious, loss of appetite, mood swings, annoying, painful rashes...you get the idea.
But most important:
WHAT WAS YOUR EXPOSURE???
Unless you are a medical professional who was accidentally stuck with a syringe from someone known to be HIV+, the only reason to begin PEP is if you engaged in unprotected vaginal or anal sex with someone known to be HIV+.
No exposure involving protected sex, oral sex or any variety of anxiety-provoking "small cuts" and "vaginal fluid" (especially in a massage parlor/strip bar setting) would warrant such extreme measures.
