I will take 5mg and pass out in half an hour. I don’t use it regularly though, just when my bedtime starts creeping and I need to reset it.

Most of the time I take 10 mg. of melatonin at bedtime. Natrol or Nature Made (it's called "Sleep longer" & has GABA and L-Theanine.

I hear you on that. My doctor recommended trying melatonin and the pure zzz ones seem to help a bit but only if I keep to my routine and take them at the same time and go to bed at the same every night.

I dont take that. I don't take anything. But mornings are very hard on me trying to wake up.n

Just saw 2 video's both about daylight & evening melatonin. You should get more sunlight for nir sun lightlight which is best at sunrise or sunset making sure you are warmed by the sunlight which even goes through your cloths. Another video I watched is for tumors in the body, Each patient took 180 mg a day with most of them NOT having those druggie effects. I have been taking this for two weeks and been mostly clear headed. Other articles I read stated that most products on the market use fillers or lie about the dosage that is in each product. I would recommend finding a better resource for your supply. I will admit that before taking 180 mg a day I was taking 10-20 mgs a night also without any problems for years,but in the beginning when I was taking 3-5 mg like 10 years ago I did have some of those side effects that you are experiencing. So, I strongly believe you are not taking a pure form of it. I even use products with GABA, Valerian Passion Hops Chamomile HTP or other calming products all together with separately or in one product. Multiple B's & magnesium is also very important. Find a practitioner who specializes with vitamin's & herbs is very important. either locally or on the internet . By the way I have a pituitary tumor that has grown 1/3 larger recently so that's why I have increased my dosage of melatonin to 180 mgs. Will keep you posted on my outcome,since I am scheduled for surgery in 3 weeks unless my tumor has shrink.
