Yes... The constant cold and sickness plus diarhea. He also always blows his nose. I thought it's just allergy. And always gets sick. I wondered why a big guy would be such weak. He always told me that he got food poisoning. I was so silly that I always took care of him, brought him food during my lunch break, bought him medicine at 4am, etc... Only recently I just read that diarrhea is a side effect of coke. No wonder.
