I see you have found the awesome "social" side effect of methylphenidate
Yeah it makes me more social too as well as kills most of my anxiety, and... killing my depression for its duration in my body.
In my opinion, nothing works better than Adderall XR & Klonopin, 25mgs and 4mgs respectively in my case.
If you have sexual dysfunction swap Zoloft for Remeron, that anti-depressant HAS no sexual side effects and it works on your SA too as well as being an anti-histamine for allergies and helps nausea too.
