While the concept is definitely innovative, and the flavors are delightful, the product isn’t effective. I tend to have difficulty falling asleep, so on my 2 nights off a week I take a 5mg melatonin pill before bed; that helps me catch up on some much needed rest during my nights off. I bought this in hopes it would be more potent than the pill variant, since it’s being absorbed directly into your bloodstream via your lungs, but sadly that’s not the case for me. With the 10 puff serving size only providing 1.3mg of melatonin, even taking 20 puffs 45min before bed does nothing to assist my sleep. The idea for this is awesome, but the execution not so much.
