I've been taking it for two days and I get a lot of diarrhea. I've been drinking a ton of water and it seems like the water makes the diarrhea even worse. Could the medicine possibly be causing me to dehydrate? Or am I drinking too much water (3 liters a day, morning, noon and night)? Is it possible to drink too much water? My skin is flaky and dry and I try to keep hydrated because it's been so hot, but I go to the bathroom so much, I'm concerned I might be doing some damage to my body.
