Gatorade has electrolytes that help against dehydration.
Tea has caffeine, so i'm not sure how good that is.
Try juices
Try drinking apple juice. Water makes u vomit more .. try eating crackers it settles ur stomach ..
Crystal light makes a lemon /strawberry flavor and its helped me with my nausea ..I can't drink regular water or carbonated drinks. The crystal lights helps a bunch (:
I went & bought some crystal light & ill try some lemon in my water & see how that works. I go to the dr soon.
Try adding like mio or crystal lite to the water, or get some flavored water.
Or cut juice with water. You don't want all the extra sugars from the fruit juice
Ya any fluid you can get will be helpful. Tea sparkling water even maybe water with lemon in it or any kind of citrus might help.
Maybe try some juice??? Or I wonder if something like Gatorade would be ok. Or maybe add some flavoring to the water? Or milk with ice cubes in it?? Not sure, just some ideas.
