To clarify - my 250mg experiences (done twice now) were 50mg doses repeated every 6 hours or so. Basically, for me the acute effects of aMT taper off after about 6 - 8 hours. Yes, you still get some residual stuff going on but it is drastically reduced.
So, I like to continue having fun in a safe environment (say over a long weekend) and why shouldn't I? I'm hardly some kind of crack-head caning moron here...just because I enjoy pushing my experience a bit further and longer than others doesn't make me any less responsible than you. In fact, I can almost guarantee that I take my drug usage much more responsibly than most. For example, aMT is the ONLY substance that I use at the moment.
I can see an argument for people seeing me say I took 250mg over a weekend and then going apeshit on the freebase. To clarify - this was HCl salt and probably a slightly degraded one at that. It was also taken in 50mg doses, never more. There's the harm reduction out of the way.
Now, onto the thing about redosing. I find it quite effective actually. The first three doses will stack up on one another quite nicely, after that you are just prolonging the euphoria (not even really the stimulation, just the euphoria). This is fine by me. Some people don't enjoy 36 - 48 hours of trippy headspace (and I hardly call this a pure psychedelic, it is MUCH more forgiving than even mushrooms or mescaline), but I do. Each to their own. I sort out my life so that it doesn't impact any responsibilities, lock the doors, unplug the phone and away we go! I enjoy it this way and so do some others who have done it with me.
We're not just rolling around laughing at the ceilings, at these doses we have had some of the most intense conservations that really got to the core of some very deep-seated issues. In one instance, for one girl I was with, there was a psychological breakthrough of an intensely therapeutic kind and she has been happier and filled with life ever since. I've had the same experiences with personal issues from my past, although not quite as powerful.
So to say that the way I have experienced aMT is somehow worse than anybody elses is bollocks. For me, the intensity and length of the experience turn it much more into a spiritual/therapeutic trip than I imagine any of you have ever had on this stuff. You're missing out, if you like and are prepared for that sort of thing. It requires everyone to be experienced and on the same page, a small group of three or four can then bond on such a deep level that I have never seen on anything else; and it is not as superficial as the bonding on MDMA or Alcohol. It is a bonding that hits the very core of your being.
But beware, for there be dragons...
This isn't some drug for kids to take in their bedrooms whilst the parents are downstairs, or for students to take the day before class, or for adults to take the day before work or some other commitment. But treat aMT with respect and higher doses can lead you down some very meaningful experiences.
