Hello gagrl: I'm sorry I don't really have any useful suggestions for you. I have had difficulty sleeping when I have been on some psych med's in the past. (I was on Cymbalta, though, & it was not one I had problems with.) When I did have problems, I took Trazadone for sleep.

I still have difficulty sleeping sometimes. But it is unrelated to psych med's since I no longer take any. When I do have difficulty, I typically get up & do sort-of a walking meditation... walking slowly around-&-around our dark & quiet house. I focus light attention on each foot as it touches the floor. Thoughts come-&-go. I don't dwell on any of them... just let them arise & fade at their own pace. After an hour or two of this, when I go back to bed, I usually fall asleep. I've tried Melatonin. However, I found that if I wasn't going to be able to sleep, taking Melatonin didn't help. Plus it always made me groggy the whole next day.
