I switched from Lexapro to Celexa last Thursday. I was taking 10 mg of Lexapro and I am now taking 20 mg of Celexa. I have been pretty much a walking zombie ever since. The first two mornings I woke up with severe headaches that wouldn't go away until the afternoon. By Sunday those disappeared. Now I am dealing with problems sleeping, tiredness and feeling funky. I know that it is because I switched from one med to the other overnight so I just gotta tough it out for now.
Wish there was an easy way to get through this icky phase.
