Cold sore question--?

I use Abreva every time I feel the "tingling" (meaning I'm about to get a cold sore). The Abreva prevents it from occurring, but I am wondering...Does anyone else get them as much as me? I mean, I get the "tingling" almost every day! What is the meaning of this??? And does anyone know a good way of preventing them?

I get cold sores by not having enough sleep, not drinking enough water, being really stressed, getting my period soon, or being out in the sun a bunch.

I had problems a few years back with them. If you go see your doctor he can prescribe a medication that you can take and they won't come back (unless you stop taking it, etc). It has worked really well for me and I have been cold sore free for a number of years.

I was told that a cause of cold sores was an imbalance of acidity in digestion. If your acidity level is up, the ph does not have a chance to combat the virus. Supposedly if you drink a small amount of a water/baking soda solution, the balance of acidity and ph will return.
Also, I get cold sores often too. I alternate between Abreva and Camphophanic for Cold Sores. I was using strictly Abreva, but it started to become ineffective. I will alternate which ointment to put on so that I do not build up a tolerance to either product.
