Great replies everyone. I agree a lot with Jason Porter - Water is the fluid that will keep you clean. Learn about keeping the blood pure with good food. Stop going to the doctor. No one in my immediate family goes to a doctor, and it's been that way since before I was born. I'm named after Jethro Kloss, author of Back to Eden, a very famous health book.
I eat and assimilate good food 24/7, with occasional fun times thrown in for good measure. I use products from Richard Schulze, who has his store in Santa Monica. He's got the purest and most potent herbs I've found, and I've been around this stuff since forever. It's expensive, but the best. Order online. http://www.dr-schulze.com/abp_1024x768.asp
During a show use his:
Superfood
SuperTonic
Echinacea+
Cayenne
I use this stuff whenever in high demand situations...toured Europe for 8 weeks and worked very hard...no sickness.
Wash your hands often especially when people are sick around you.
Get a juicer, and use it at home when you are not working. I remember Peter Devlin joking with me about my juicer I took on the road for a movie in Utah. Temperature extremes, many exteriors, and long hours; never got sick once, always had energy. I'd juice up the carrots in my room at the end of a day and go to bed. Wonder what the person next door thought (strange sawing sounds?). Now I use a Champion Juicer, the best simplest juicer there is. Got a used one Ebay for $60.
Old School has it right with family, food, fun, and projects for thyself. Jeff's got the sleep in check, for sure that's needed.
cheers,
