"i suffered from early waking insomnia for about twenty years. it mattered less when i was younger, i could always keep going. in the last few years it became a problem to the extent that i refused invitations/ avoid travel because i know i&#039;ll be sleepy and the anxiety of having to do something the next day made the insomnia worse. i could fall asleep quite happily at 9pm, but then wake four hours later and often not fall asleep again. i tried sleep restriction, zopiclone, various natural remedies.nothing worked. i have now been taking doxylamine succinate for 5 weeks and it has been life changing. i take half a 25mg tablet when i wake at 1am. it takes about an hour to kick in, but then i get a further 3-4 hours sleep. heaven."
