No after affects
I've been taking Melatonin for about 48 yrs. And has no after affects. I take it as needed. I've taken 1mg to 5mg. depending what kind of a day I've had. The pill is very small. I like the orange and peppermint flavors. The best time to take it is about 45mins. before you would go to bed.

Source Natural is a good brand but I find 5 mg too strong and need to split them.
As a person with sleep problems due to illness I can say that this melatonin works to get me to sleep sooner. I don't sleep most of the night without it and this brand works better than others I've tried. I can't use 5 mg though and find 2.5mg better. I'm cutting them in half and don't plan to order 5 mg. again.

Works wonders for me
I love this product since it works immediately (due to the sublingual delivery system). I also appreciate that I can halve or even quarter the tablets easily.
