Clors, I'm struggling with insomnia too. I take hot baths, drink chamomile tea, read, and listen to calming music to get ready for bed. Doesn't always work though ... so I have just learned not to fight it. If it means that I have to stay up until 2-3 am until I'm good and tired, that's fine ... I'd rather fall in bed dead tired and sleep well for a couple of hours than go to bed at a normal time and toss and turn all night.
A drink isn't the solution but you already know that. Our bodies have been so used to having "help" getting to sleep that it takes time to readjust and learn how to sleep normally again. It's tough but it will pass. My sleep patterns are finally starting to even out again, although I do still have 2-3 nights a week (like tonight) where I struggle to get tired. Hang in there.
