My doctor refuses to prescribe sleeping tablets for me on the grounds that they are addictive. She, however, has no objection to me taking Nytol, as long as I pay for it myself. At the same time she is happy to prescribe for me Tramadol (a weak opiate) by the bucketful, even though I no longer suffer the pain which made the prescription necessary in the first instance.
Thus, if I am unable to sleep, then two Tramadol combined with one Nytol sends me into blissful repose, from which I awake in the morning fully refreshed.
