herpes simplex
"I have been on Acyclovir for 3 days following a first outbreak of genital herpes - having never suffered with anxiety or depression, I've been crying about an hour after taking each pill. Feeling anxious, depressed , sweating, abdominal pain, short-tempered and very nauseous. Mood swings aren't in the side effects but they should be, as countless other people on similar forums have experienced the same."
