I started 30 mg Duloxetine almost a month ago and so far have been very happy with it.  Zapped my life long anxiety within a week. Felt like a new person. After reading other statements I feel very lucky. I continue to feel supported by it but have been having trouble falling/staying asleep (but I'm not anxious over it!!! : ).  Last night I took an Excedrin PM which helped. I am wondering whether taking the Duloxetine every other night might help stabilize my sleep. Anyone had this type of experience? Maybe I should just take the PM - I worry about medication and liver problems - I'm 67.
