Lavender and lemon as you know lavender is great for relaxing and lemon oil just like lemon juice calms your mind and healing effects too add with sandalwood or almond oils or coconut( fractionated is less oily ) it holds the effectiveness of essential oils longer taking a hot bath and cold shower before then quickly warn up with hot towels and use your chosen essential oils, place a slice of lemon if you have one near you bedside , and enjoy good restful nights sleep . I like to turn off website hour before it helps you unwind easier . Read the psalms 27 is very precious . Sometimes use eucalyptus oil with tea tree oil or lavender and Orange oil use no more than three to diffuse and give your room refreshing air , Hope this helps Kind regards swift HUG from England keep smiling and stay safe 🙂
