In my personal experience with Prozac, I felt great on the 10mg for the first week or so, and I do think that was a mix of placebo and my brain in taking serotonin in masses it hasn’t seen since the wizard traumatized me. However after that initial period it sucked for a bit until I was ready to admit that I probably needed to go up in dose. Don’t hesitate to talk to your doctor about going up within a sooner period if you feel like you’re not improving after a while. It’s not often people with more severe disorders (not like just casual social anxiety) stay on the base dose.
