I've been on Zoloft for 10 days now. The first 7 days I was on 25 mg per day and felt horribly depressed and anxious. I'm now on 50 mg per day and feel like a zombie. I've become very apathetic. I could sit and stare at blank walls all day and be entertained by that. I drink massive amounts of caffeine to try to get myself going. I'm not sleepy, just a zombie. I don't care about anything. Still a bit anxious, though, as I'm falling behind in school. Does this go away?
