I've been taking Lexapro for 6 months but I didn't like it so I asked my doctor to switch me to a different medicine. She switched me to Wellbutrin but by the 5th day I started to feel nauseous and have a really bad headache. It felt like a really bad case of the flu. I stopped taking the wellbutrin cold-turkey. It has now been 2 weeks since I stopped lexapro. My head feels horrible. Sound and light feeling like it's killing me. My eyes are acting weird and I have blurred vision. I can't seem to concentrate. I've had a non-stop headache that's excruciating. And whenever I sit up or turn my head too fast it only makes everything worse. I was wondering if this could be withdrawal from lexapro. I'm at my wits end. I cant stand this feeling any longer. I've been to the ER twice and an urgent care center but no one knows what's going on. I've even had a CAT scan and everything was fine. I'm going to my doctor soon but until then I don't know what to do. I can't do anything but lie down on my couch all day. I'm going crazy. I really need some answers fast. Please.
