-Need a way to fall back to sleep easily:
Try some lavender or orange essential oils to help with insomnia.
Stop lying in bed thinking about all that you have to do, this won’t help you sleep. Instead, try a calming yoga pose: Lying on your back (in bed of course) with palms upward and feet hip width apart, inhale deeply and count to five, then exhale slowly counting to eight. Repeat up to 20 times.
Deep breathing can also help to relax you to sleep, lay on your back and breath deeply enough that you move your belly. It is called belly breathing, and is great for anxiety as well. The deep breaths will help to relax your body and help you fall to sleep easily.
Try reading, studies show that this will help distract you from the anxiety that might be keeping you awake but also is a workout for your eyes making them more tired and drowsy.
Warm milk. I know this is what your grandma used to do right, well it works. Milk contains tryptophan an amino acid that your body converts to serotonin and melatonin. Both of these hormones help to improve sleep. Adding a little honey to your warm milk will help relax your nervous system as well.
Try keeping some peanuts nearby. Sometimes all you need is a little food in your tummy to put you back to sleep.
Soft jazz or classical music or even an orchestral melody will help relax your body and put you to sleep by lowering your heart and respiratory rates.
