For future reference, 10ml of white vinegar in 200ml of distilled water seems to do the trick. Thanks, all. I'll let you know how tonight goes.
-----------------------------------------------------
Well, I ended up taking something closer to 25mgs (15mgs initially, 5mgs an hour later, and another 5mgs 60-90 minutes after that) since I had eaten shortly before trying this, and it was taking more to feel any effects.
Other than the sweating as I came up, this was extremely gentle and blissful. While there were no visuals to speak of, I found myself in a very relaxed and dreamy state of mind. It felt like I was able to direct where it went, switching at will from a body sensation to a more internal one. There was nothing pushy about this at all...quite malleable. It also facilitated one of the most absorbing and consuming sexual experiences I've ever had...just totally losing myself in the pure energy of the moment.
The high itself was really no more than ++, but I would do this again without hesitation.
