So my cold sore was full blown and massive by the time I took valtrex Thursday evening, I took 2 pills, went to sleep for 12 hours, and took another two pills. So far, my sore still looks pretty big and gross. Do u think after 1 or 2 more days it will start seeing a little improvement and begin to scan over? I can't handle this! I'm hopeful though, all the reviews seem wonderful.
