Hey, here's a thing: I was on 10mg for a year, and it did almost nothing, and I went up to 15mg and literally everything changed overnight (which breaks my mental model for how that works, but fine). I was doing frequent mood check-ins and there's a dramatic effect from the day after I went to 15mg. Could be placebo, but I was super skeptical when the doctor suggested increasing the dose. Now I'm on 20mg 4 years later and it's perfect.
