I started on Cymbalta 5 days ago . The first dose (30mg) made me kind of sleepy and that was good b/c I haven't been sleeping b/c of the anxiety and panic attacks. But now I have a belly ache pretty much all day and no appetite. And about the first 5 hrs after I take it my heart rate isnt right. And the insomnia is worse now than before. I read some of the post on here about antidepressants , so should i wait it out and see if the side effects get better or call my doc and get something different. And some of my anxiety is the cf but I think some may be hormonal b/c I am 45. Has anyone else had anything like this with this medication.
