Hi Pam
Congratulations on your first day back at work. As you say, things will get easier. It's particularly tough in early days of Type 1 diagnosis, as there's so much to learn about getting balance of insulin, food and activity etc right - and your pancreas may be having a honeymoon phase which means it irregularly decides to have a last gasp and issue some insulin, irrespective of what you've injected. Not sure how much physical activity you're doing as a manager in a hardwear store, but if you need to move things or walk long distances, then make sure you have some sweets or glucose tablets in you pocket (actually, have them to hand whatever you're doing), so that you can have a couple before doing activity and if you feel yourself going hypoglycaemic. When newly diagnosed, you may feel hypoglycaemic when actually at normal levels, as your body has got used to higher levels - but this will ease gradually. If in doubt, treat as hypoglycaemia by eating something.
Not an easy employment situation for anyone just now...
