Sounds awful... Once I tried 12mg intranasal and I ended up sitting it my room staring at the wall just wanting it to wear off really bad, and I was really paranoid. Higher doses don't seem to do anything pleasant for me when it comes to NDRIs.
Personally I find intranasal and oral dosing to put my right on edge, as you describe; paranoid, overstimulated, sweaty and wanting it to end.
After talking to DS_ I ended up trying smoking it and 20mg smoked is a good dose for me, doesn't put me on edge and is far more euphoric and clear headed than eating or sniffing it, which I find largely unpleasant with 5-15mg quantities spread over a few hours!
