Try not to worry about it all, don't want more stress than you can avoid..
But yes common sense should get you through..
Just remember to carry plenty of snacky type foods (more so with the whether as it is now) plenty of what ever you use for an hypo..
Remeber you insulin, meter and plenty of test strips...
I would do more test throught out the day for the first week or so, until you build a picture of how you BG's are reacting, this will also help you be proactive in avoiding any hypo's...
If you take long acting insulin in the morning, keep this to the same time as moving this around will faff up your control, if this means that you have to take it while traveling, then try to get the time as near as normal when it's convienient to do so.. If moved keep a very close high on your BG's...
On your first day, let the person that you will be working know that you are a diabetic, and what to whatch for that might indicate a pending hypo...
If you have any meetings to attend then ensure that you take a BG before starting and ahve something ready to munch if you have to, near at hand..
You will must likely find that the thought of it all is a lot worse than sorting it out, as you are having to think ahead to a certain extent, about all the things we do automatically everyday...
Good luck, and I hope you enjoy your placement
Nearly forgot, don't forget to write down your data, BG's etc, so that if any problems that you can see whats goiong on...
