sleep and anxiety

has any one ever had insomnia caused by depression anxiety or medication???

I have always slept well, other than getting up to urinate. But recently I have suffered from anxiety, and some combination of the anxiety and the Lexapro I am taking has caused me pretty significant sleep problems. Basically, I cannot fall asleep without taking some sort of medication -- and even then I awake during the night. I have tried melatonin (which did not do so much good), benadryl (worked ok), and xanax .25mg (works pretty well, but I don't see that as a long term solution). Doctor also gave me a beta blocker to take an night, but thus far I cannot sleep with that unless I also take something else. So, you are not alone....

Thanks SC. I am wary of supplements and "natural" products because of the lack of FDA regulation/approval. Some of them are probably great and maybe others are dangerous. But it is hard to tell which is which.
