The small tablet dissolves fast and is easy to take.
Size: 60 Count (Pack of 1), Style: Melatonin 5mg
Mostly I don't even taste the tablet under my tongue, and I hardly feel it. Occasionally I taste it, and it's a bit bitter. I wait to take it until I'm feeling sleepy, and I'm asleep within 5 minutes of taking it. I think it helps me to stay asleep for several hours.

They do work but they taste terrible!
Size: 60 Count (Pack of 1), Style: Melatonin 5mg
I got these for my special needs son after his doctor recommend trying melatonin to help with some sleep disturbances. They definitely help him go to bed calmly and even stay in bed through the night but I have to bribe him to get him to take them because the taste is so bad!
