This is a vicious cycle. The definition of insanity is doing the same thing over and over and expecting different results. Increasing the dosage does not work. Dosage needs to be *decreased*.
What bothers me particularly about this is that I really *need* melatonin to sleep, but only small quantities. As the pills get larger and larger, it's hard for me to get what I need. Plus the side effects of larger doses are making it more likely that the substance will be banned as a nutritional supplement and not be available to me.
