completely agree with your said but i would need to mention a obvious point of me that solve my problem for short perioud, we so called disease.
1.) been quite seldom get sick like heavy flu after having this disease started.
2.) every time i try to throw my flu away even dint feel sick, it will decrease the affected range or the disease will stop
3.) if i can't even feel i have flu, will try to eat some thing spicy or hot, it will helps but only try it when less or no people around you because it will seriously affecting them as well during your flu or sweating in few minutes period
