Well, it's hard to answer not knowing any real specifics about your situation - diet, bmi, etc BUT I will say that there are some things you can do none the less.
I'm not sure what qualifies as "hoaky" in your book - I guess in mine it generally means someone trying to sell me something of dubious quality...
I prefer "natural" health care myself and generally choose health care options for my family that are the easiest and least invasive while still being effective.
In general, a healthy body is always the best defense against illness. Try building a little extra exercise time into your day. Right now my kids and I are heading to the local high school's track for some walking /running in the mornings (they take outdoor toys and play while I run the track), but even a little cardio type exercise or yoga here and there as you find the time can be helpful. Yoga can help keep your muscles limber, builds strength and endurance, and the stretching can help release buildup of toxins stored in the muscle tissue that can put a strain on our immune and other body systems.
Also - diet. Diets that are high in sugar can encourage onset or flare up of certain diseases or imbalances in the body - including auto-immune disorders. Maybe try gradually scaling down the amount of juice/ pop/ meat you may be ingesting while slowly increasing the amount of fresh veggies and salad. While I'm not a vegetarian myself - I am working on shifting the balance of my diet since more and more studies are showing that a "raw food" or vegetarian diet can do wonders for our bodies' ability to stay healthy, and I'd love to be healthy enough to really enjoy living life to the fullest, even after my kids are grown. Even just the shift I have managed in my diet has helped me feel much healthier!
On a last note, I will share something that we use in our house to ward off, or speed healing when we are getting sick. It's free, and I'd be willing to wager you have some nearby. Queen Anne's Lace tea (feel free to google it for pictures). Queen Anne's Lace is a wild carrot (it's where we started when we began selectively enhancing carrot strains to arrive at our current store-type variety. The whole plant is edible (although the "carrot" turns bitter in the plant's second year) and rich in vitamins A and C. We use the leaves to make a tea that has a good deal of medicinal benefit, and tastes good too. The natural compounds contained in the leaves contain chemicals that are antiviral and antibacterial, some that act as antihistimines, and some that relieve stress. We VERY rarely end up heading to the doctor. We just brew a cup of Queen Anne's Lace tea at the first sign of illness and more often than not - problem solved - if not immediately, then shortly.
I know you may find this "hoaky" but remember - I'm not trying to sell you anything - I'm just honestly sharing with you something that works wonders for keeping my family of 8 healthy, and it's free - probably growing in your backyard to boot.
I have personally used it to treat food poisoning (the same compound in the leaf that helps you to relieve stress also relieves stomach spasms -aka nausea) and it soon quieted my nausea while the anti-bacterial properties went to work on the offending food in my tummy. We use it for allergy/sinus problems, colds, and even just this week it seemed to just whisk away a daughter's urinary tract infection that had gotten so bad (she didn't tell me) that she was literally screaming in pain when she went potty one afternoon. One cup before she went to bed, and next morning she was like brand new and said she had no pain. Even my husband swears by it. I continue to be amazed at just how much this plant has made a difference in our ability to overcome illness. It tastes so good too - I sometimes drink a cup after a stressful day, as a warm light-flavored way to relax and unwind.
My only side notes if you do decide to try it next time you feel sick: 1) Make sure you know what it looks like (google lots of images) since you will have to pick your own - actual queen annes lace prefers sunny, well drained soil and often grows along the edges of fields - not in marshes like a slightly similar plant. 2) If you're pregnant, don't consume large amounts. Queen Anne's Lace can help bring on your period, -I've used it for this too - and there is a chance that drinking the tea while prego could encourage labor or miscarriage. (in fact they used to use the seeds of Queen Anne's Lace as the olden version of the - morning after pill) so steer clear or limit yourself to a weakly brewed cup 3)Since you can't buy it anywhere, you may want to consider drying some so you have some on hand during the winter months. To use it, take 1 tsp of the dried herb or about a palm-sized amount of fresh leaves and steep in hot (but not boiling) water for 10-15 minutes.
These are the things that have worked well for us - diet, exercise, and if someone starts to get sick anyway - a good herbal tea :)
Whatever you choose to do to aliveate the problem, I hope it works well for you! It's such a drag being sick anyway - but far more so when you have kids AND work!
Best of Luck!
