I was going to say what dose of what SSRI but do understand serotonin syndrome is not a great way to enjoy your time make sure you don't get to trouble I assume that's why your asking else do some looking into what you were taking but 2-3 weeks is not all that long relatively speaking and you could be in clear. When in doubt start with less dosage than normal for you. I have always felt amphetamine were the best anti depressant well that and opiate of course until you get more depressed with come down or withdrawal.
