Since recovering from Shingles, I have been resting and avoiding over-activity. However, I need to resume some type of moderate exercise to relieve stress and maintain my cardiac system. I also should start taking a multi-vitamin. I already eat a very healthy diet. My sleep is not good -- I tend to wake up at night every time I roll over, and have to get up very early for work (before 5:00 AM). Other than improving in these areas, is there anything else I could do, but give this more time to heal?
