hey girl! lightning sometimes does strike twice- but you'll make it i'm sure!! to your gastroscopy: i know it's not a comfortable thought that someone puts a tube down to your stomach- but when you're about to swallow it, close your eyes and think of sitting at a dinner table and imagine that you have to swallow a big bite- i'm serious- i asked a medicine student who's only got 2 exams left what to do at a gastroscopy the barium thing is not really bad- you won't be affected by that in any way...
hope i could help u and fingers crossed for your exam!
