Pristiq has been working really well for me - but there are some days that I get excess anxiety. I told my therapist about this and he told me that I may have extra cortisol (stress hormone) that needs to be controlled. I've been taking a supplemental pill from Amazon to help with this - usually take it 2-3x a week, when super stressed.
