You are type 1? Lows during the night suggests your insulin dosage may not be right. It could be that your basal is too high or that your night time bolus amounts are too much.

Change can cause real disruptions. Were you traveling across time zones? Jet lag and re-adjustment can be very difficult to cope with. The body can have definite 24 hour rythyms with basal requirements and this can mean that what is normally happening during for example the afternoon, shifts to the night time during jet lag. Again requiring adjustments of insulin and perhaps strategic snacks to compensate.

Also, if you were travelling, was your activity level changed about? This too can mean adjustments are needed.

It's hard to give much more specific advice than that. Really, the best general advice I can think of is to test, test, test, and learn, learn, learn - both what happens with certain foods and situations, but also read up on different methods to successfully live with your condition. On a day to day level, interacting with your diabetes, in ways such as adjusting your own doses if you see a change of trend, is the only way to keep on top of it that I know of. There might also be bigger changes you could make such as changing insulin, changing diet or moving to a pump. If you are unsure, not confident or feel you need help, best to try and set up good communication channels with an endo and diabetes educator so you can access their help on a regular casis.

Have you been to an endocrinologist recently to see what they say about your current situation?
