Fair enough.
All medications are going to have side effects.
It's long been known that for people with depression, as they start to get better, very often one of the last things to improve is their subjective mood.
There's another dangerous time you didn't mention, and that's as patients start to improve and when they're discharged from hospital. Very often as their mood is improving, their energy is improving, and their concentration is improving, sometimes when they've had suicidal ideation from being depressed, what can happen is that now they have the energy to carry out those plans they originally had.
