The mhs address on the treatment page is good.

He is very busy, and also I would always allow a weeks grace just in case he is out of the office or on vacation. If he does not reply within 2-3 days though, and assuming he is in, there is a good chance your email just slips down a list of read or unread, put off to do later, and then just gets 'lost'.

My own tactic, which seemed to work most of the time, was to email him on a Sunday. He sometimes answered the same day from his iPhone, but more usually on Monday morning, where I assume he found my email close to the top of his start the week list.

Edit to add, make sure your email includes all the info he is likely to need. The less to-ing and fro-ing due to him not have enough info or clarity on what it is you are asking, then the better.
