Third trimester insomnia

Jg • Pregnant with TWINS after mc in April 2015 -looking forward to this journey - trying my best not to be anxious
Omg anyone have any tips on fighting  third trimester insomnia. I am up every hour sometimes every half hour to use the bathroom and then seem to be awake from 3am onwards 😢 I'm feeling exhausted but just can't seem to get comfortable enough to stay asleep - restless legs, move a certain way feel like I can't breath - any tips/suggestions would be greatly appreciated!
