I drink plenty of water so much it makes me sick. .Like 8 to 10 bottles a day. Usually after eating I can throw it back up . And also have diarrhea with it. Now I'm having horrible cramping as if I'm on my period which is impossible since I got a hysterectomy in 2013. My doctor is stumped. Anyone else have this ?
