I am on this. Been on it for quite a few months now (3 or 4) fairly low dose (150 twice daily).
my initial reaction extremely good, I got a nice stimulation effect from it (which was useful for me) and quite a pronounced mood boost. I tried to raise to 300 twice daily and experienced quite a lot of anger and irritability. Went off it for a month or so, got a lot worse mentally, and still had a bunch of it left so hopped back on.
Social anxiety was worse in the beginning though, no doubt about it. But several months in I have (I think) less social anxiety. It is marginal, and hard to know for sure.
The thing is, the effects are subtle so they could easily be placebo, but i was pretty suicidal near Christmas, and am quite a way from that now. If its Moclobemide, then its worked great (but I tend to vary a bit anyway over time). I am more confident in its ability to help with depression than social anxiety.
Side effects, virtually none. A little dizziness on standing sometimes and a slight weird head pressure thing / headache (not sure how to describe it), may be unrelated.
No sexual sides, no weight gain, no lethargy (am doing a diet monitoring calories and metabolism is def fine). The stimulant effect isn't there anymore (only lasted a few weeks).
I strongly recommend it if only because it has pretty much no sides. Maybe it will do nothing for you but you might get a subtle benefit like I seem to have.
