I'm not a Doctor yet so don't take my word to heart especially since I don't know your current state. As for brand wise, whether Zoloft is good or Paxil or whatever, it doesn't matter the brand.. THere is no research done to show any antidepressant is better than the rest. If the only problem you are having is sleeping I would STRONGLY NOT recommend sleeping pills. They are highly addictive (even the ones that say "non habit forming"). If you have having problems sleeping you need healthly sleep NOT drug induced sleep. Look at it this way, you sleep like crap now and you start popping pills and you sleep like a baby, why would you go back to not taking them? (I have experience in this, not just a professional view, I was addicted to Ambien during my back stage). As for the AAS and PCT, I don't think serotonin has anything to do with test/ estrogen levels so you should be okay. I had the same problem as you are describing. I just couldn't sleep b/c of so much on my mind. I never went the Zoloft route but I did use Lexapro. It is specially made to treat anxiety and once I kicked ambien I got on this stuff and once I started sleeping better I just up and stop taking it and I sleep fine now
