I ALWAYS try and say nothing about Zoloft because i hate making sweeping statements, but search the forum for Zoloft, i've read a few positives, but i know for me it defiantly wasn't the one and it's always (or usually) the first thing the GP in England will give you. I have family members, myself, people i've talked to and read many stories who could not stand it.. but that doesn't mean it's not for you or anyone else reading this.
What i will say is you are on it, so you will know if it's not for you, if it makes you worse, it's not you (after 6-8 weeks)... the next one another GP in England gave me was Mirtazapine and i've tried 14 medications, it was for me. So don't give up, try another medication. Good thing about Mirtazapine is it's listed under PTSD which DP is thought of as a subtype (on the NHS anyway), so easily available under the NHS, but first i'd get past 8 weeks, say it isn't working and they will probably hit that next
