I have GAD and Depression, both severe but my anxiety is much worse. This is my first time switching between meds, and I feel absolutely terrible. The reason I'm switching is because I'm hoping to not gain as much weight with this drug. However, my doctor never told me anything about Prozac so I have no idea what to expect. Can I have some advice and personal experiences from others? I don't have therapy or anyone to go to, so anything will really help. What can I expect from Prozac? I heard it's really rough to start on.
