Yeah, you're in a new environment and it takes a little time to adjust. I've had a lot of sleeping issues myself, and something that has worked for me was getting a sleeping mask.

Getting to bed, and getting out of it the same time every day will help. Even if you're just laying there trying to sleep - eventually the routine will set in.

Stay away from caffeine and eating a healthy diet will also help.

Drinking chamomile tea can help.

Getting something like ZzzQuil might be helpful until you get back onto a good sleeping routine.

Meditation help too - as it helps relieve stress.

Good luck.
