It seems ok no better or worse than other brands/forms of melatonin I have used in the past only far more expensive. I use it regularly and have nothing negative to say about it other than it is ridiculously expensive when compared to other similar products.
I do want to say that some of these reviews seem so completely fake. One worth mentioning although it doesn't seem fake is the 4 star review based on nothing. Review literally states that product hasn't been recieved but customer was comfortable giving it 4 stars. I personally found this pretty humorous.
SLEEP FAST® ENHANCED MELATONIN SPRAY
Generating follow up emails to review a product I haven't received yet isn't great service.
Will update when / if I receive my order.
I'm sensitive to all meds, so I only used 3 sprays at bedtime (not the recommended 6) and I fell asleep well, and noticed that it helped me get back into sleep easily every time I woke up (which is my biggest issue).
I have found this product easy to use. I really appreciate that I do not have any side effects unlike diphenhydramine. I tried a cheaper alternative spray finding it less effective. I am definitely sticking with Sleep Fast.
