I was suffering from mild diarrhea, so I prepared ORS in a copper bottle from which I drink water and went to sleep. After waking up in the morning, I drank a large quantity of the solution. After an hour, I developed an ache in my stomach, and after that, I started experiencing severe watery diarrhea which was green in colour.I also vomitted once. Intending to make more ORS solution, I threw away the remaining ORS solution, and that's when I saw that the solution and turned blue in colour. I went to a doctor in the evening, who gave an injection for the vomitting and some medicines. The duration of the bowel movement has decreased, and the watery diarrhea has also started becoming a little solid. However, it is still greenish in colour. Should I worry about it, because I have been reading online and it seems I am suffering from copper poisoning. My stomach pain is not there now, I am having normal urinary movements. I am drinking a little quantity of ORS regularly from a glass jug.
