insomnia
"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'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."
