The first day it all started off with feeling like my mouth was very dry, a couple of hours later I started to feel dizzy. So I though that maybe I was just dehydrated, I started to drink a lot of water, but it wasn't that because when someone is dehydrated their urine tends to be a very dark yellow and mine was very clear and waterlike. The next day my mouth still felt very dry in the morning, however by the afternoon it was gone. Also throughout the day the dizzines kept on going away then coming back, I also felt very tired (fatigued). The third day my head hurt and my stomach was in pain at times. Im very confused I don't know why ive been feeling like this, it had never happened to me before. Can someone help me and tell me what this could be? Or if someone has experienced this too?
