"Fab better than expected"

Product Review:

"The only sleeping aid I have found that works. I have prescription sleep aids that work worse than this."

Service Review:

"They are quick, discrete and very easy to use. It was far easier to do than I ever expected. Getting my prescription online was far easier than in-person and felt much more private than asking at the desk of the pharmacy 100 per cent would recommend."
