Duloxitine

Tell me if I’m barking up the wrong tree, years ago I was put on antidepressants and then I had neck issues so my antidepressants we changed to duloxitine 2 birds 1 stone, when I got pregnant I lowered my does to 20mg it was the safest while I was pregnant, I never went back to my original does, I was thinking going back up would help with my issues
