I don t know what illness I m experiencing. It started when I got cold due to lack of warm clothes when I was running errands back and forth to the stores last week. Then, I was also sleeping late and lacking sleep due to waking up to feed the baby. Then, Wednesday last week, I started feeling cold. I thought it was from lacking sleep so I drank 3 cups of coffee that day. Also, I was cleaning the garage which I found cold. That day was cold in Chicago. Thursday, I lost my appetite. I was feeling sleepy and tired. So, I drank 2 cups of coffee. I was still running errands at night for my baby s 1st birthday party yesterday. Friday, I felt the acidity in my diaphragm. Then I lost appetite that night. I felt my back and feet cold. I was having like flu-like symptoms without the fever and colds. Then, when I ate, I would vomit what I ate. I was having diarrhea, too. I would drink Dayquil. After the medicine wears off, I will have the same symptoms again. For my diarrhea and hyperacidity, I would take Zantac and Pepto-Bismol. My muscles are weak that I get tired easily. I don t know if it s because I haven t eaten right. In 5 days, I lost 7 lbs already for not eating. I will only eat crackers.
