Do NOT quit them cold-turkey.
I quit them without talking to my doctor for a number of reasons, the primary one being that I don't think my depression was helped by them, and my biggest problem symptoms were from something else anyways. Being on them actually made me anxious and miserable, because I had such a hard time getting my Rx filled on-time from the various pharmacies I tried. Got the runaround a lot, and wound up experiencing withdrawal symptoms on numerous occasions just from waiting for my refill, and my fear of being at risk of experiencing them again due to circumstances out of my control was worse than any benefit I gained from being on them.
So I took the few pills I had left one day, cut some of them into halves and others into quarters, and did a DIY weaning over the course of 2 weeks. This was WAY too short, and I experienced the full brunt of the withdrawals anyways for about a week. I dissociated almost to the point of feeling disembodied, I slept a lot, couldn't think straight due to brain fog, and was pretty much a walking zombie. I also experienced a symptom that doctors don't really recognize as real, but is still pretty widely reported: they're called "brain zaps", which is sort of like the sensation of a small, faint electrocution in every nerve ending in your body. It happened a dozen times a minute at first, usually in time with lateral eye movement, then once ever few minutes a week later, then less often over course of the next month or two.
They never went away completely, though, and some people report feeling them even years later. I get them once in a blue moon when I lay down to go to sleep sometimes.
In other words, don't quit SSRIs cold turkey if you can avoid it. You really don't want brain zaps for the rest of your life.
