I have difficulties falling asleep at night. Tried using the pregnancy pillow and drinking hot milk before bed. Any other non medication suggestions I can try?

When I was in my third trimester I had problems falling asleep as well. My usual bedtime was about 4am! Try taking a hot bath in lavender scented shower gel to relax your senses before going to bed. I found that listening to music helped me go to sleep better and I took the effort to ensure my bedroom was in an ideal sleep inducing environment. The air con would be on before I stepped in, lights would be dimmed and bed would be nicely arranged. If I still couldn't sleep I would get my husband to give me massages then hug and pat me to sleep like a kid. Hahaha. Maybe it'll work for you too.
