Product Review:

"Excellent value and service "

"Easy, worry-free ordering!"

Product Review:

"I've tried other sleep aids but nothing really works. However, now that I've found Sominex, I won't be trying anything else. Normally, I can get to sleep but I wake up a couple of hours later and I'm wide awake, finding it difficult to get back to sleep. Sominex is ideal for me, it actually keeps me asleep for longer! I'd recommend anyone to try it."
