Hi Adam
Welcome to the club nobody asked to join! LOL
It's a lot to take in all at once, so please - don't try! Like the tortoise and the hare - you will get there one heck of a lot quicker by going slowly and giving it all a chance to sink in. The 4 jabs a day sounds awful to start off with, but honest, you do get used to it pretty soon. Also testing.
And please - do get the Ragnar Hanas book which Northerner mentioned - it's excellent and it doesn't read like a science textbook from school - written in language that we can all understand.
Good luck and remember - there are never, ever any silly questions about diabetes! So keep on asking whenever you want or need to ask, and ask whoever is available at the time. That's the beauty of forums like this one, we don't work office hours and you don't need to make an appointment .....
