SSRIs and SNRIs just didn't work very well for me. If they had an positive effect at all, it wasn't enough to rise above the proverbial noise.
Coming off of them wasn't too bad though. I got the brain zaps, but those were easy to cope with.
More than anything the whole experience was a waste of money, and what finally fixed my problems was retirement and a greater attention to my health.
They work so well for some they are miracle drugs, and for others they do nothing or have negative effects. This is typical. We still don’t fully understand why or even why they work at all.
Have you looked into mirtazapine (tetra cyclic), vortioxetine (serotonin modulator) or atomoxetine (SNDRI). Atomoxetine has been a god send for me.
