Not that much more too add about the purple domes. The pill looked blue, with purplish speckles. I had two on the night about 2 and a half hours between them. I'll agree with the hit hard and die quick comment, although I had two so I can't really comment on the effects of one, I was going strong for 6 hours easily, dancing and talking my arse off. My vision went quite blurry though, I couldn't even read the screen on my mobile for a few hours, that's never happened before.
