apaddyinuk - i'm surprised to hear that people sometimes have a bad reaction to antihistamines, i always thought it was a pretty harmless drug! i've never had a problem with clarityn, the one i'm prescribed. apparently it's the only one pilots are allowed to take whilst flying so i guess it makes sense that cabin crew should be allowed to use it, too...but i guess i'll find out for sure soon enough. i can easily do without them if necessary. thanks for your post - i get terribly paranoid sometimes... i think it's all the waiting!
teamilkandone - thank you, that's very reassuring and i feel much better!
