Srini,
Please also Google Herpes and follow high Lysine low Arginine diet. It truly does make a difference in the foods that you eating.
Once I stopped eating legumes and nuts, the frequency and severity of pain of Herpes Zoster Shingles decreased markedly. I am immunocompromised, so I am going to get it no matter what, but some people don't get episodes at all.
I found the Acyclovir did not help me. Acyclovir is the oldest drug, and Famciclovir the newest formulation.
I am so excited for you as Alaska is a fantastic and exciting trip! Please Email after the holiday and let me know how you enjoyed the journey!
Again,
Best Wishes
Merry Juliana
