Don't do it! I did that years ago once - coz i couldn't sleep but for the whole of the next day I kept asking my line manager to let me go to sleep under the table - i kid you not. If you can't sleep take a HALF of the recommended dose.
funny that, because i often take the full dose (two tablets) and I'm fine the next day .... always. Obviously must affect people differently. My daughter uses them too from time to time and she's never missed a days work or felt sleepy with them.
One tab usually works for me-and yeah I feel groggyish -but hey the sleep you get is fab- -failing that one of Legends legendary 'over the centiury threads' usually works for me.
DTH???
BTW -IAM NOT THE MESSIAH !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I take Nytol when I am having trouble sleeping and feel quite refreshed the next day. I always try and ensure that I have got 6 - 8 hours sleep so that the effects have had time to wear off before I wake up.
The nytol in the blue wrapper disturbs my sleep and gives me the weirdest thing - restless legs! Like pedalling all night. I use Kalms - works fine for me.
