From what I hear, foxy opens your senses without giving you the euphoria that accompanies ecstasy use. So on foxy you will notice more from what you touch, taste, smell, hear, see. Normally, your brain seems to screen out a lot of stimulus. Foxy takes the screen down, so you notice a lot more. Like how your tongue feels in your mouth, how your teeth taste, how your shirt feels rubbing against your chest, etc.
In a hectic environment, this is BAD. Too much stimulus can be overwhelming, disturbing, unpleasant. However, in the right environment, it can be as good as rolling. My friend did this at a strip club, and the lap dances felt as good as if he were rolling. On another occasion, he did this at a concert and when everyone was cheering at the end, it was like the cheers were a cloud that lifted his mood up and up and up until he was in a state of amazing and pure contentment and joy that was as good as the euphoria you get from rolling except that his mind was completely clear not like the stupidity that accompanies rolling. Also, foxy lets you do light shows significantly BETTER than rolling. Faster, better coordination, better pattern perception.
So, anyway, foxy is very dose and setting dependent. But if done right, it is as amazing as ecstasy.
I've also heard that, with the right doses and timing, taking foxy and e can make you super-roll harder than you ever thought possible. But please note that this combo may be dangerous, both physically and psychologically, and having been involved in one trainwreck with this combo I guess I would not recommend it unless you keep the foxy dose very small, like 6 mg, and do it early in the evening like before or with your e, so you are not peaking on the foxy when your roll fades.
Anyway, those who think foxy is one of the less useful, less enjoyable, less interesting RC's...well, I suppose to each his own, but personally I think you just have not done it in the right setting and dose.
