I didn't expect to enjoy this stuff - for some reason I thought of it totally as a knock-you-out thing. I really like it though!
First time was purely to halt a mephedrone binge. I was planning to take 0.5ml - but a couple of people said I would even feel it, so I should go for 1ml. I went for 0.75ml, and FUCK, it hit me like a train. Think everyone else has described how it feels...
I was amazed by how intense it was, and I don't think that's typical. I think that must have been the no sleep no food thing -- it certainly wasn't any milder because of the stims (suspect different stims, different interactions?). I redosed a while later (I don't know how long :S) and I felt a bit sick that time, a bit overemotional.
The obligatory "I took too much":
Figuring I was very sensitive to it, I took 0.5ml. But this time not on the back of a meph binge -- actually had had sleep and food. It didn't seem to do anything.... I waited 30 mins then had another 0.5ml. I only waited 15 mins before utterly stupidly having 1ml, in a "let's see where this gets me" way.
Didn't pass out -- but after about 45 mins I decided I felt shit enough to go lie down and sleep it off. Well, I didn't sleep.... I had many strange half-dreams about running around my flat scribbling on the walls with a whiteboard marker. Then I had an interesting sex dream involving Drew Barrymore. (mugabe: "It's ok, I like Drew.").
Sort of slept a bit then... then woke up feeling pretty normal, if a bit sick. Went to bed, slept fine, right as rain next morning.
I also tried a 1ml dose, but that was too much for me too -- was too out of it. I think my definition of "too much" is probably not the same as others, as I'm sure many people love being totally out of it. At the time, I felt AMAZING and proclaimed this to anyone who'd listen - but I don't remember the it as being fun, just as being too much. Not sure that's an accurate recollection.
