At my clinic I get a note to check my on-line information, so it's usually only a couple of days. I also get a note from the my Diabetes Support Team but snail-mail takes a little longer.
Were I you and I thought things were moving too slowly I'd have a chat with your medical folks.
I view managing my diabetes as my job, and I am The Boss. In that role my success depends on using all of the resources available to me, which includes my medical support team. I expect them to call me on my failings (although I have very few of those), and I in turn will point out theirs.
Hope that helps - Guy
