YAY! I am happy your sis is feeling better! I know how you feel, we have been to
disneyland 5 times and I have been sick for 3 of them!!!
First time was when I was in kindergarten, it was about 9 oclock, and we were leaving about 4 in the morining to drive to disney. Well, as my parents are finnished up last minute packing, I got to my mom and say "mommy, my tooth hurts!" and my mom looks in my mouth, and turns out I have an absess tooth! Well, so my parents scrambled around, called my dentist, he perscribed meds over the phone to some pharmacy that was 24 hours (if you dont treat an absess tooth you can get physically sick such as vomiting) so that we could go on our trip and then have it pulled when i get back. YUCK. lol.
second time was when i was in first grade, had the flu our entire trip, never threw up, but hardly ate and felt horrible.
third time we were driving the coast when i was in fourth grade and i threw up all over the car. YUCKY
thank goodness our last 2 trips i wasn't sick! Hope you thought my stories were funny and i HOPE HOPE HOPE your sis feels better!!!
