I had this problem since I was young, my metabolism is slow. I need to drink a hot coffee every morning to get my waste (poop) out. Since then my body got used of the hot coffee. It was 3 days ago when my husband prepared lemon, orange and cucumber for me to eat before going to bed. The next day I was awaken by the urge of going to the toilet. The feeling is great having to poop every morning for 2 days. He also suggested to drink tea if I ate to much or feeling full.
