Why food combining and alkaline diet help me in 2 weeks?

Hi!
I've done that twice. It takes only 2 weeks when my Acne is dry out leaving clear face, rosacea gone, hair gets thicker and shiner, and I have a very white teeth.
I've done a food combining with plenty of vegetables, fruits, and chicken with salad, drink a lot warm water with half lemon. I throw out smoking and self-gratification and no any suplements. I look and feel goregous!! But... why?
I thinking I have a low stomach. My symptoms:
gas
bloating
thining hair
Chronical fatigue syndrome
Acne and rosacea
blurred vision
poor memory, no concentration
mild depression

Why alkaline diet is helping me even if I think i am low in stomach acid? I am confused.
I must admit that i don't ejoy food combining. It is too hard to keep on it on daily routine. And I love cooking. What should I do? Tweet
