I took Zoloft for depression for over 12 years and quit taking them about 5 months ago. Long story, but I really didn't need them any more. Unfortunately, because of the way the Doctors are so paranoid nowadays, it's nearly impossible to get them to support you in ceasing taking any long term meds even if you have a good reason. So, I just tapered off on the amount I was taking over several months and finally quit. It was very hard, even after taking 1/3 of what my prescription was for several weeks. Man, that stuff really had it's hooks in me.
I also took Xanax and some other prescription sleep aid for a couple of years and quit taking that stuff because I was addicted to them as well. I quit taking them 2 years ago. That was also kind of rough not being able to sleep for a month or more. It didn't take too long before I didn't need them. Unfortunately, I pretty much had to quit them cold turkey.
I do feel better though. It's kind of nice being able to feel emotions that I simply hadn't felt in a couple of years because of the meds.
So, I've been completely prescription drug free for about 5 months now.
