Fluoxetine
"I was switched to this coming off of Lexapro, from which I was having severe withdrawal symptoms: dizziness, nausea, a poor time sleeping. I got switched to Prozac because I felt Lexapro wasn't covering all my anxiety enough, and so far the experience has been...eh. Like a lot of other reviews have said, you'll feel great for the first few days and then things'll probably go downhill. I often feel I'm not in my own skin--empty. I have strange dreams. My self-motivation is poor, and I can't spend money without crunching numbers fifty times over. I can never seem to do things I enjoy without feeling guilt about something else. It saved my ass from the side-effects of Lexapro, but I'm not sure if the 20mg dosage is going to be enough."
