Speed King, I'll share this with you. I originally wasn't going to mention it, but I saw where you made note of "slight visual distortions", and I can relate my experience, as well. I had done 4 of the Z, in the manner I mentioned, plus 150mg of the tramadol, the latter being orally. And, as usual, a few beers. Let me tell you, I actually experienced as much visual hallucination, as I ever have, on anything. Not quite sure how or why, but it was there, and for a while. Mainly in the form of weird moving shadows, (the meth heads call them shadow monsters), but it wasn't disturbing or scary. I knew what was happening, and I just took it in, fascinated. The other visual hallucination, was really odd, trippy, foggy looking "streamers", coming off various objects, if I stared or focused on them long. It was crazy, and very impressive, to say the least. Additionally, another thing that I experienced at that time, was a serious loss of balance, and coordination. It was bad! It was as if I was wasted drunk, like when you stumble, and lurch around, falling down, and all that. Yet, I wasn't drunk from alcohol, nowhere close. I think I had 4 beers total, and that's not a lot for me. But the overall combination, definitely had me well beyond practical functionality. I actually had a notion for a moment to go to a friends house, and then I thought, no way! I can't even walk, much less drive, and so I settled to the couch, and just let it run its course. A very profound experience, to say the least. Different strokes, and to each his own, as I always believe. Just thought I'd relate that particular experience. I'm about to try a variation of it again. Wide awake, can't sleep, I went and put a new kitchen faucet in tonight for a friend, and to my pleasant surprise, he was kind enough to turn me on, to a completely different groove, which I thoroughly enjoyed. Now its time to relax and sleep.
