Every so often I suffer from insomnia, the sort where you fall asleep OK, but wake up and hour or two later and then that's it, can't drop off again. I treated myself to this a couple of months ago, but had not yet tried using them. After a week of insomnia as described, I was exhausted and desperate. Last night I put a handful in the bath, an hour before bed and soaked as instructed. Let myself mostly air dry to let residue stay on my skin, and had my first decent night's sleep for a week!! Better than a sleeping tablet. I am now 100% convinced and converted.
