What triggers an outbreak of HSV2 for you?

This question is only for people who currently have HSV 2. Is it certain foods or drinks, clothing, activities, stress, sleep, etc. I take 500mg. of acyclovir twice a day, eat well, exercise and have no other health issues, yet I am still having outbreaks (or at least they begin-I double the dosage to curtail the outbreak). I haven't had in a year and am afraid will cause a real problem. I have had HSV2 for two years now. Thanks for any help.
