I am having really bad diarhea for 3 days now and i have to go to the bathroom like 8 times a day. I had to miss work today because my stomach was really giving me a lot of pain. I have taken Pepto Bismol and it only works for half an hour and then the pain comes back. So i have to take it every half hour but its says not to exceed 2 days taking it. So i dont know what to do? I cant go to the doctor because i cant afford it):
