That is a good question!  I too, worry about the whole throwing up thing that comes with too much drinking.  My daughter is only 8 with SWCAH and we are teaching her now about how to care for herself (ie. drinking lots of water or gatorade when in the sun or playing sports along with salty snacks, tell a grownup when you don’t feel well, etc.)  We are also continually discussing smoking, drugs and alcohol (ie. danger of and staying away from, etc).  I do know that when my daughter vomits from car sickness, it is just usually once, and we give a triple dose of Cortef, saltines and water, and she is usually fine.  It’s when she is vomitting along with fever, due to an illness, that we usually end up in the ER on IV fluids and meds.  I don’t know what will happen when she’s older, I hope that what she learns now will help her make the right decisions in her future.
