This is great, just want ot thank you.  Well worth my $5.  Do you
think I would have gotten an answer if I was only going to pay $2.50?

I would let you know how my sister's mother-in-law pans out.  Her
serum Na was only 114 and she was dizzy, confused and vomiting,
starting 2-3 days into Azithromycin.  But then she was having a
bronchitis at the time too.

Thanks for asking the question.  As to whether $2.50 would have been
enough -- I'm sure all researchers have different criteria for
deciding whether to answer a question at a certain price.  This
question was not complicated and did not require much research, so the
price was probably appropriate for the amount of effort required.

I hope that your sister's mother-in-law gets well soon.

very prompt and precise!
