Sandman does help me fall asleep so I give it a thumbs up to that. My problem is that I don't stay asleep like most people with long term sleep issues. I'm forever looking for that magic pill. It is tasty so I have no problem getting it down. The dropper on the other hand is hard to dial in the correct dosage. Squeezing it can give you the correct dosage however, squeezing it into the mouth it does not deliver the whole amount.
