After awhile, I was getting these insane headaches, like stabbed in the brain with a rusty knife type headache. Those lasted a few weeks.
And then came the brain shivers. Moving my eyes, or rapidly turning my head, would cause an electric shock sensation that, from what I've read, was similar to what people having a stroke experience. Like lightning in your head. It wasn't painful like the headaches, but it was well beyond annoying, if not completely frightening. I'd sometimes lose my balance and fall over.
I then made the mistake of quitting cold turkey. This was my first AD and my psychiatrist hadn't informed me of how bad an idea that was, and I was stupid for not reading the insert when taking it. After a few days of hell, I went back on it and tapered off.
I understand if it is effective for a lot of people, but I certainly know I'm not alone in my experiences with it.
Zoloft was much softer, but really didn't do much for me.
