In addition to the recommendations you've received, I would try taking L-Lysine capsules - at least 2,000mg a day. This can slow down the peeling cycle. I pasted this from another post on curezone:
"l-Lysine, an amino acid, provides nutritional support for the body's natural defenses. l-Lysine is particularly helpful in maintaining healthy gum and lip tissue.
Considerable research indicates that L-Lysine nutritionally influences Herpes simplex most effectively in conjunction with Vitamin C.
L-Lysine promotes the absorption of calcium from the digestive tract and it is involved in both bone development and the production of collagen.
It helps in the production of antibodies.
Lysine is utilized by many hormones and enzymes
Lysine is necessary for tissue repair
L-Lysine is a necessary building block for all protein in the body. L-Lysine plays a major role in calcium absorption; building muscle protein; recovering from surgery or sports injuries; and the body's production of hormones, enzymes, and antibodies."
