I have been having non stop diarrhea for 2 days any advice?

So about 3 days ago I had a heavy feeling in my stomach. Like a full sponge or something. Then same day my bowels were really weird. Not diarrhea but irregular. Yesterday I had diarrhea about every 15 minutes. Everytime I eat something it turns to liquid. I tried Kaopectate an anti-diarrheal and upset stomach reliever but it didn't seem to help much. I went to bed and through out the night got woken up by the disgsting bubbling in my stomach. Today has been the same problem. Another thing yesterday when I was having problems it was a cloudy color almost clear. Today its like black. I have been trying to drink lots of fluid to flush it out but nothing seems to help. Any doctors in the house? Thanks
