Immunity

Torri
So for the past four months I've been constantly sick. I've increased my work out dropped a lot weight drink a gallon of water a day but I've been getting sick constantly back to back. I had MRSA in the back on my throat for two months and now i have bronchitis and laryngitis. I'm taking vitamin c and eat an orange or grape fruit a day... Anything else you ladies have to help out with this stuff?
