panic disorde
"Years ago, I took Zoloft while going through chemo, and it helped me cope better. I wasn't crying as much. But, now you can only get generic, so I tired Sertraline for depression and panic attacks. It wiped me out. I could not keep my head up unless I had slept about 12 hrs each night.

When I tapered off, I began to experience some cognitive issues. My typing speed dropped, and my error rate went up. I'd type things (words & phrases) I didn't intend to, and not type things I intended to. A neurologist said the med was likely helping my serotonin levels, but, when I tapered off, my brain was having issues. Varied doses didn't help either problem, so I tapered off. Tiredness stopped quickly. Typing issue slowly improved over 2-2.5 months."
