CO2 Laser & Rhinoplasty: Herpes Simplex Virus 1 (Oral Herpes)- Should I take an anti viral drug as a precaution before surgery?

Next week I am undergoing rhinoplasty, lower blepharoplasty, a u-lift, and CO2 laser on my face, neck and chest. I've gotten cold sores since I was a little girl. I am wondering if the stress from these procedures - particularly the CO2 laser - might warrant taking an anti viral drug before surgery to prevent an outbreak. The last thing I will want is a herpes outbreak. I've rarely taken oral medications for my cold sores so I really don't know if oral medication is appropriate. Thank you.
