Im seeking quality sleep. One post said if you wake up during night and take a low dose sublingual melatonin it will be fast acting and help you get back to sleep pdq. ??? I have some melatonin capsules. Can I open them and put the powder under my tongue and get the same effect or are the two made differently. All the sublingual melatonin I looked up have artificial or natural sweeteners and my system wont tolerate either.
