Having been to NY myself, but on Lantus, If possible get ahead of yourself, change times before you go, though as you'll soon be jetting off, just change to the times you get there. As your body clock will change too, you may have a time of being high but continue with new times of where you're at & stay alert of activity (a lot of walking!!!) On return do same as going, or if possible change times back to GMT. Not too hard when you get used to it, just remembering to do it, being caught up in excitement, meals, travel etc!! Are you ok for packing meds & stuff in holdall or cases?? Enjoy your time there, fantastic place!!
