cold sores
"I got this when I had already had 2 crusty cold sores and just got rid of 1. I get them alot and they don't care-they show up for no reason! I took the 2 and then 2 later and it helped clear those up in no time at all, but when I start on a new cold sore I notice the 2 now and 2 later isn't working but the doctor won't change the script so I'm doing a bit of testing at home to see what helps.  I haven't had a cold sore often enough now to say if taking 2 now 2 later for 2days helps or 4 now and 4 later for 1 day is best. I still have the painful blisters and they still came in the overnight to the 2nd day-not more just the ones that came the first day became fuller. This was on the 2 now and 2 later. I did catch it right when I felt the itch."
