I take 20mg Cymbalta every day. My work day got the best of me and while I thought I was taking my Vitamin D (which I had just taken and forgot), I took 40mg Cymbalta and realized it after I swallowed. I've been on 30mg before and it was a bit too much (I felt incredible but it gave me the poops). Is 40mg something I should be concerned about? (Minus probably getting the poops... oops.)
