Since December I have had two head colds, the Flu, and now Bronchitis!! I can't take the Flu shot because of allergies. What can I do to increase my immune system?? Most of the research I have found suggests exercise (yeah, I'll get right on that) and sex!! I have Bronchitis and feel like at any moment I'm going to actually cough out my lungs and the "experts" say a good roll in the hay with my hubby will fix it right up. 5 bucks says a man wrote that report!! ;-) Any "real" suggestions??
