Yes and no. It's incredibly useful for certain subsets of people. For others, it seems to be an added cost for little to no utility. In many cases, the effect is not too significantly different from placebo.
I have taken various types of psych meds, and I was actually disappointed that I didn't feel dramatic reactions like some people claimed. With antidepressants in particular, a lot of people talk about feeling "emotionally blunted" on them. As someone who was suffering with emotional intensity, it was a side effect that I actually desired and was disappointed when I didn't get it. I never felt controlled or altered in much of any way outside of some initial fatigue.
So I think a lot of the negative effects of these meds might also have some basis in placebo. The meds are not all bad.
After a while of trying different meds over a year, I've "settled" on one particular med and been very stable since. Is the med helping? I still have no idea. But it isn't doing anything negative that I can tell and you cannot deny the objective reality of my improvement. My improvement is no doubt multifactorial, but if it's doing good for me, then why not just continue? I still feel like me. I am just happy and functioning.
