is there anything important going on in your life right now (or before) that could be subconsciously stressing you out and not allowing you to relax?
i've also had trouble sleeping before and i've done relatively well going the herbal, natural way. for me was d/t outside circumstances and i fully support the others' comments on making SURE it's not sleep apnea.
1. i used johnson's lavender and chamomile baby bedtime body wash/lotion
2. sprayed my face and pillow with rose water
3. get in bed and meditate
4. this one is weird but i sleep better when my wrist is bent.. like the back/top of my hand is touching the mattress. i've been doing it since i was a baby lol.
5. get into this position
i hope you're able to find what works for you soon!!!
