I have been an insomnia sufferer from 20 years of night shifts. I was looking for something that would help me that would not have serious side effects or be addictive. At first, maybe a week, I felt dizzy just as I was sleepy enough to fall asleep. That did go away with time. I have sun sensitivity/allergy and Rosacea plus overly sensitive eyes, so I am not a sun lover. I don't know if this works for me bc I am deficient in melatonin or if it will work for someone who gets lots of sunshine, but I am thrilled I found help. No smell or taste. Only complaint is it is a dry pill and although I have zero trouble swallowing pills, these tend to stick to my throat a bit. My nightly snack is a protein drink, so I just swallow the pill and follow with that. I would say it is worth a try
