I used to take Cymbalta, but it made want to sleep 18 hours a day. My pdoc & I thought it was a side effect that would wane, but it continued to affect me this way. I finally told mt pdoc that I couldn't exist like that anymore & was taken off it gradually & placed on a different med. Now I take Pristiq, which is working pretty well so far.
If the excessive sleeping doesn't clear up by Tuesday, then definitely talk to your pdoc about a switch. I felt so clear-headed after I tapered off & Cymbalta was out if my system (abt a week after the last dise for me)!
Good luck and hang in thete!!
