I have gone through 1g of 5-APDB by now, mostly mixed with ethylphenidate.

I'll give you one of the trips.
T - Swallowed a bomb of 80-100mg 5-APDB.
T+0:30 - Starting to feel the effects, somewhat more sociable.
T+1:00 - Okay, now I get a little body rush, similiar to that of MDMA. In a positive way of course. But firstly I get that rather initial part.
T+2:00 - Okay, effects are now fully here. Very good feeling, I am so in love... :D If anybody has done aMT, then this is not very much different from the stimulating part of aMT, as it is also rather a stable empathogen, unlike MDMA which has a very intense rush in the beginning. I am quite sleepy though and have no psychedelic effects. But at full effects I cannot really function 100%, meaning I am sleepy and am not thinking as when I am sober, but I do not want to get caught (with people who must not know that secret of mine), so I decide to insufflate about 60mg of ethylphenidate.
T+2:10 - I am very clear headed now. Lost that head load, meaning psychedelic part (though it is very mild with 5-APDB, nowhere near to MDMA or even less to aMT). I am somewhat confused. Feeling is good in many ways, but a bit confusing which I really dislike. Despite this, I can now think way better and am not sleepy anymore. I still have that super body feeling, that I am in love and feeling awesome and so on.
T+4:00 - Trip ended, to another bomb...
In conclusion I would say, that it is a very nice drug, especially when with people who shouldn't notice, as it doesn't mess up your brain as much as, for example, MDMA does. It doesn't have any real psychedelic value though, but it is a very good sedative, especially when combined with something stimulating (because it really lacks energy).
