// Jonah, no disrespect but do you distrust your gp/dentist so little that you require a second opinion on AB. ? //
there is no evidence Jonah that people who seek 2nd opinions on AB actually act on them. There is in fact quite a lot of evidence they read the opinions and just say 'oh'.
The usual order used to be - amoxil and then if there is a reaction give erythromycin but it OK to reverse the order.
and yeah I don't see why you don't ask the opinion of strangers if you want to.
