Why am I nauseous when I drink water first thin in the morning. This is not new. Been this way for 20+ years and since I m only 38 it s basically for as long as I can remember. But I m trying to drink more water throughout the day and if I can t get this thing under control I m going to have to cut out the early morning water. I only drink it in small sips because I know what s going to happen. Room temperature, cold, bottle, fridge, tap, nothing makes a difference.
