I've only used Zoloft (Sertraline). It got my bad headaches, loss of appetite, extreme anxiety/depression to go away, thank goodness. I needed it back then and it did me good. I will say it seems to have permanently lowered what was my raging, to the point of being embarrasing, libido, but it's not like it doesn't work anymore, its just not as easy as it used to be. Most SSRIs have this effect from what I understand. I have contemplated starting it again as life have become quite stressful, but I have managed to keep things under control for now. I don't ever remember being so impulsive before or during use of the Sertraline, but I struggle with impulse control more now than I used to.
I have read SNSRIs (Serotonin and Norepinephrine Selective Re-Uptake Inhibitors) reduce the libido lowering side effect. Or combining SSRI with welbutrin, wich i believe is just a Norepi reuptake inhibitor.
If you are getting a medication like this, as in all cases, I seriously recomend a good discussion w/ your Doctor/professional, and take everything else from us with a BIG chunk of salt. Hopefully you can get some good insight and questions to discuss w/ him/her from our comments though.
Good luck man.
